500 errors usually mean that the server has encountered an unexpected condition that prevented it from fulfilling the request made by the client. This is a general error class returned by a web server when it encounters a problem in which the server itself can not be more specific about the error condition in its response to the client.

In many cases this is not an indication of an actual problem with the server itself but rather a problem with the information the server has been instructed to access or return as a result of the request. This error is often caused by an issue on your site which may require additional review by our support teams.

Our support staff will be happy to assist you in resolving this issue. Please contact our Live Support or reply to any Tickets you may have received from our technicians for further assistance.

There are a few common causes for this error code including problems with the individual script that may be executed upon request. Some of these are easier to spot and correct than others.

File and Directory Ownership

The server you are on runs applications in a very specific way in most cases. The server generally expects files and directories be owned by your specific user cPanel user. If you have made changes to the file ownership on your own through SSH please reset the Owner and Group appropriately.

File and Directory Permissions

The server you are on runs applications in a very specific way in most cases. The server generally expects files such as HTML, Images, and other media to have a permission mode of 644. The server also expects the permission mode on directories to be set to 755 in most cases.

Command Syntax Errors in .htaccess file

In the .htaccess file, you may have added lines that are conflicting with each other or that are not allowed.

If you would like to check a specific rule in your .htaccess file you can comment that specific line in the .htaccess by adding # to the beginning of the line. You should always make a backup of this file before you start making changes.

For example, if the .htaccess looks like

Then try something like this

Note: Due to the way in which our server environments are setup you may not use php_value arguments in a .htaccess file.

Exceeded Process Limits

It is possible that this error is caused by having too many processes in the server queue for your individual account. Every account on our server may only have 25 simultaneous processes active at any point in time whether they are related to your site or other processes owned by your user such as mail.

With SSH (shell) access, you can view the processes running on your account. Simply type this command:

Or type this to view a specific user's account (be sure to replace username with the actual username):

Once you have the process ID ("pid"), type this to kill the specific process (be sure to replace pid with the actual process ID):

Our server administrators will be able to advise you on how to avoid this error if it is caused by process limitations. Please contact our Live Support or open a Ticket. Be sure to include the steps needed for our support staff to see the 500 error on your site.

Symbolic Representation

The first character indicates the file type and is not related to permissions. The remaining nine characters are in three sets, each representing a class of permissions as three characters. The first set represents the user class. The second set represents the group class. The third set represents the others class.

Each of the three characters represent the read, write, and execute permissions:

• r if reading is permitted, - if it is not.
• w if writing is permitted, - if it is not.
• x if execution is permitted, - if it is not.

The following are some examples of symbolic notation:

• -rwxr-xr-x a regular file whose user class has full permissions and whose group and others classes have only the read and execute permissions.
• crw-rw-r-- a character special file whose user and group classes have the read and write permissions and whose others class has only the read permission.
• dr-x------ a directory whose user class has read and execute permissions and whose group and others classes have no permissions.

Numeric Representation

Another method for representing permissions is an octal (base-8) notation as shown. This notation consists of at least three digits. Each of the three rightmost digits represents a different component of the permissions: user, group, and others.

Each of these digits is the sum of its component bits As a result, specific bits add to the sum as it is represented by a numeral:

• The read bit adds 4 to its total (in binary 100),
• The write bit adds 2 to its total (in binary 010), and
• The execute bit adds 1 to its total (in binary 001).

These values never produce ambiguous combinations. each sum represents a specific set of permissions. More technically, this is an octal representation of a bit field – each bit references a separate permission, and grouping 3 bits at a time in octal corresponds to grouping these permissions by user, group, and others.

The .htaccess file contains directives (instructions) that tell the server how to behave in certain scenarios and directly affect how your website functions.

Redirects and rewriting URLs are two very common directives found in a .htaccess file, and many scripts such as WordPress, Drupal, Joomla and Magento add directives to the .htaccess so those scripts can function.

It is possible that you may need to edit the .htaccess file at some point, for various reasons.This section covers how to edit the file in cPanel, but not what may need to be changed.(You may need to consult other articles and resources for that information.)

There are Many Ways to Edit a .htaccess File

• Edit the file on your computer and upload it to the server via FTP
• Use an FTP program's Edit Mode
• Use SSH and a text editor
• Use the File Manager in cPanel

The easiest way to edit a .htaccess file for most people is through the File Manager in cPanel.

5. Test your website to make sure your changes were successfully saved. If not, correct the error or revert back to the previous version until your site works again.
6. Once complete, you can click Close to close the File Manager window.

The permissions on a file or directory tell the server how in what ways it should be able to interact with a file or directory.
