1. Syntax Error: this occurs either when the user misses something or when the code has incorrect syntax while trying to add code snippets into WordPress. The result is a PHP parse error and is viewed as:
   Parse error – syntax error, unexpected $end in /public_html/site1/wp- content/themes/my-theme/functions.php on line 263
   The error message indicates erroneous entity and its location in the code. To fix this the correct syntax needs to be corrected. In majority of cases, the culprit is a missing bracket or some inaccurate unexpected character in the code.
2. Internal Server Error: Also viewed as 500 Internal Server Error, this usually happens when the server is unable to identify and recognize the problem. The user is left on the lurch to detect the problem on own.
3. Database Connection Error: It is obvious that the reason for viewing this error is the inability of connection between website with the database. It may spell doom for a novice but it can be easily solved by correcting database login authorization (database host, database password and database username. The cause may also be unresponsive or corrupted database.
4. 404 Error: Viewed when user visits a single post, the next step is to browse through all sections of the site together with the admin area, looking out for permalink settings. To resolve this issue the user needs to reconfigure permalinks settings or update their rewriting rules manually.
5. Sidebar below Content Error: When sidebar appears below instead of next to the content, the cause is related to themes. While adding code scraps, failing to close html div tag or adding an extra closing div may cause breakage in theme layout. Further, using disproportionate width in CSS and not clearing the float appropriately are other triggers.
6. Memory Exhausted Error: The cause of this error is depletion of default allocated memory size limit and is indicated by a white screen or an error message : Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2348617 bytes) in /home/username/public_html/site1/wp- includes/plugin.php on line xxx
7. White Text and Missing Buttons Error: This problem occurs when concatenated JavaScript does not work in user’s admin area, missing or corrupt TinyMCE files or issues with some other plugins that modifies or extends TinyMCE shipped with WordPress.
8. Locked Out of WordPress: When user forgets password and has no access to the password recovery email, it may result in being locked out of WordPress admin area. Additionally, plugin or code that wrongly tries to make some changes into admin section and the action of changing all usernames and passwords due to hacking of WordPress site may be the reason too.
9. Login Page Refresh and Redirecting Issue: When the user tries to login to WordPress dashboard and is redirected back to login page, the user needs to check the values for site url and home url in options table.
10. Image Upload Issue: Sometimes all images are viewed as broken and on uploading to a post using media uploader, it results in error and all files appear as broken. This occurs due to incorrect file and directory permissions in installation of WordPress.

Although this list is not exhaustive, these common errors and their solutions will enable the user to breeze through most of them.

At timesWordPress Hosting creates memory problems and fatal errors like :
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 78 bytes) in /home/…/ on line 806

For this problem, the best solution is to increase the memory of WordPress.
For increasing the memory in few steps :
Step 1 >> Login to your Control panel.
Step 2 >> Then enter to “File Manager”
Step 3 >> Try adding this line to your wp-config.php file :

define(‘WP_MEMORY_LIMIT’, ’64M’);

Step 4 >> Now save your settings.

Remove Fantastico

Just solved the problem myself. In case someone faces the same problem, here is the solution:

1. Go to your fantastico data directory which can be found in File Manager.
2. Click on the installed_in_root.php file and simply delete it.

Now, you can reinstall Joomla through Fantastico again.

To use Fantastico to remove an installed script, first log into cPanel, then scroll down to the Software/Services section and click on the Fantastico De Luxe icon.
On the left menu, click on the script you would like to remove. This will bring up the script information on the right side. Locate the installation that you want to delete and click the remove link. Follow the on-screen prompts and Fantastico will remove the script and database associated with it.

Manually Removing a Fantastico Script
The first thing you should remember to do is get backup for your web site files and databases just in case. See this link for more information on how to do that:

–> Create a backup with cPanel

Also when deleting the files and folders related to the script in question, it is a good idea not to clear the trash until you have checked and made sure things are functioning as they should be.

Step 1 – Clear Out Your public_html Folder
[ If you installed it into a specific folder, then you will need to delete that folder only. For example, when installing WordPress, you might put it in the folder called, “blog”. Delete the entire folder with that name, and your job is done.]

Step 2 – Remove the Related Databases

This can be done via cPanel’s MySQL database management screen. See this link for more information on that:
–> Setup a MySQL Database

Step 3 – Edit/Remove References in Fantastico
Now you need to remove the script from Fantastico. Login to your hosting account via FTP or cPanel’s File Manager, and locate the .fantasticodata folder. Inside of that folder, find the folder that matches up with the script you want to uninstall.

>>Delete the file installed_in_root.php.

After this is removed, the script should then be able to be installed in the root of the primary domain or addon domain.

To confirm it has been removed from Fantastico, go login to your cPanel account, click Fantastico, and now it should not be listed as one of your installed scripts.

How to Root Password in Linux

It happens sometime that you can’t remember root password. On Linux, recovering root password can be done by booting Linux under a specific mode: single user mode.

To recover Root Password by following steps

Go to single user mode:

To use single user mode first thing is restart your system. Using GRUB, you can manually edit the proposed menu entry at boot time. To do so, when GRUB is presenting the menu list (you might need to press ESC first), follow those instructions:

1. Use the arrows to select the boot entry you want to modify.
2. Press “e” to edit the entry.
3. Use the arrows to go to kernel line.
4. Press “e” to edit the entry.
5. At the end of the line add the word : Single ; S or 1
6. Press “Enter” to go back to the parent menu.
7. Press “b” to boot the kernel.

It gives you a shell access with password but there are some securities for that access to disable those securities Use following command:

# setenforce 0

For the change the Password

# passwd

Note: if your system requires you to enter your root password to log into Single User Mode then append “init=/bin/bash” after “Single” hit “Enter” to save the change.

BEST LINUX SERVER WEB HOSTING PROVIDERS

[T1 file=”/home/phphtmlo/usa-webhosts.com/tables/Hosting/dedicated_server_hosting.txt”]

Apache is the most common web server available (after Microsoft’s IIS). It has been in operation since 1996. 60% of all websites use Apache, making it more widely used than all other Web servers combined. The reasons behind its popularity are:

1. Free download and installation.
2. It is open source: source code is clear to anyone and everyone, which basically enables user to alter, optimize it, and fix errors and security holes.
3. Suitability: Apache can be used for small websites or bulky websites alike. It can supply both static and dynamic content.
4. Functions and operations that are not required can easily be removed.

What is Apache?

The Apache HTTP server is software that works in the background under an appropriate operating system. The OS should be such that supports multi-tasking, and provides services to other applications connected to it, such as client web browsers. It was developed to work with Linux/Unix operating systems, and adapted to work under other systems, including Windows and Mac. Apache binary running under UNIX is called httpd (short for http daemon), and under win32 is called Apache.exe. Installing Apache on Linux require some programming skills whereas installing it on a Windows platform is too easy, as you can run it through a graphical user interface.

Apache’s original core is basic and contains limited number of features. Its command comes from added functionality introduced through many modules written by programmers and can be installed to extend the server’s capabilities. To add a new module, the use is required to install and restart the Apache server. Functions not wanted can easily be removed. It keeps the server compact and fast to load, consumes less system resources and memory, and makes it less prone to security holes. The Apache server integrates with other open source applications, such as PHP and MySQL.

Apache server offers usage of various protocols through different ports like: hypertext transfer protocol (HTTP), simple mail transfer protocol (SMTP), domain name service (DNS) and file transfer protocol (FTP).

Working of Apache

Apache’s main role is all about communication over networks. It uses TCP/IP protocol (Transmission Control Protocol/Internet Protocol which allows devices with IP addresses within the same network to communicate with one another). In its idle state, Apache listens to the IP addresses identified in its config file (HTTPd.conf). Whenever it receives a request, it analyzes the headers, applies the rules specified for it in the Config file, and performs accordingly.

One server can host many websites and each website is assigned a different name by using virtual hosts.

Since IP addresses are difficult to remember, visitors usually type domain names into the URL address box. The browser links to a DNS server, which translates the domain names to their IP addresses. The returned IP address is taken by the browser and connects to it.

A hosted website has four main directories: htdocs, conf, logs, cgi-bin. The directories names can differ from one server to another depending on the Apache theme installed and the operating system though the roles remain the same.

Apache has been the topmost web server on the internet for a long time. It played a prominent role in shaping and making the World Wide Web. The reasons behind its success are apparent and sensing the present conditions, it will probably stay in the lead.
