Why am I seeing this page?
Error 500 usually means that the server encountered an unexpected condition that prevented it from performing a request. Typically the error occurs when the server encounters a problem, but cannot be specific about the condition that led to this error.
In many cases this is not an actual problem with the server, but a problem with the information the server is being instructed to access. The error may be caused by an issue with your site, which may require additional review by our team.
The error may also occur due to a problem on your website, which will require an additional review by our team. If you believe this is the situation, please contact our support via ticket (email) informing the situation.
Is there anything I can do?
There are some common reasons for this type of error, including problems running a script. Some are easier to detect and fix than others.
Ownership of Files and Directories
The server expects files and directories to be owned by a cPanel user specific. If you have made changes to the ownership of a file via SSH, the ideal is to readjust the owner and group appropriately.
Directory and file permissions
The server generally expects HTML files, images, and other media to have the permission set to 644. It also expects directories to have permissions set to 755in most cases.
(For details, see the Understanding File System Permissions section)
Errors in .htaccess file syntax
It’s possible that you added rules to the .htaccess file that conflict with each other, or are not allowed.
If you need to check any specific rule, you can comment the specific line in .htaccess by adding # at the beginning of the line.
Important: remember to always make a backup of this file before making any changes.
For example, if the .htaccess has this format:
DirectoryIndex default.html
AddType application / x-httpd-php php5
Try something like:
DirectoryIndex default.html
#AddType application/x-httpd-php5 php
Use: due to the configuration format of our server environments, you cannot use php_value in a .htaccess file.
Limits on concurrent processes
The error can also be caused by the high number of processes on the server linked to your account. Each account on a shared server can use up to 25 simultaneous processes, whether these processes are linked to your website or other processes owned by the same user, such as emails.
With SSH (shell) access, you can view the processes running in your account. To do this, simply type the command
fake ps
Or type in the format below to view a specific user’s account (don’t forget to replace “username” with their real name):
ps faux | grep username
Once you have the process ID (“pid”), enter the command below to kill the specific process (don’t forget to replace “pid” with the actual process ID):
kill pid
If the cause of Error 500 is the process limit, contact our team via ticket (email). When submitting the ticket, be sure to include the necessary steps so that our team can view the error on your website.
Understanding the File Permission System Symbolic Representation
O first character indicates the type of file and is not related to permissions. The remaining 9 characters form three sets, each representing the permission class in three characters. O first set represents the user class, the second set represents the class of the group and the third set represents the other classes.
Each character represents a type of permission: Read, Write and Execute permission:
- r if reading is allowed (read), – if not allowed.
- w if writing is permitted (write), – if not allowed.
- x if execution is permitted (execution), – if not allowed.
Below we see some examples of symbolic notation:
- -rwxr-xr-x a regular file in which the class user has all permissions; the classes group e others only have read and execute permissions.
- crw-rw-r– a special character file in which classes user e group have read and write permissions, while the class others has read permission only.
- dr-x—— a directory in which the class user has read and execute permissions, while the other groups do not have any permissions.
Numerical Representation
Another method for representing permissions is Octal (base-8), which has at least three digits. This notation consists of at least three digits. Each of the rightmost digits represents a different permissions component: user, groupe others.
Each of these digits shows the result of the sum of its components in bits.
- The Read Bit adds 4 to your total. (100 in binary),
- The Write Bit adds 2 to your total. (010 in binary) and
- The Execution Bit adds 1 to your total. (001 in binary).
These values never produce ambiguous combinations. Each sum represents a specific set of permissions. More technically, it is an octal representation of the bit field: each bit is a reference to a separate permission, and grouping the 3 bits at once in octal corresponds to grouping these permissions by user, group e others.
Check out some examples below that show the formation of permissions:
Permission 0755
4+2+1=7
Read, write, execute
4+1=5
Read, Execute
4+1=5
Read, Execute
Permission 0644
4+2=6
Read write

Read How to modify your .htaccess file
The .htaccess file contains directives (instructions) that will tell the server how it should behave in certain scenarios, and directly affects the functioning of your website.
URL redirects and rewrites are two common directives found in .htaccess and many scripts, such as WordPress, Drupal, Joomla and Magento, for example, add directives to the .htaccess file so that they can function correctly.
You may need to edit the .htaccess file at some point. This section will show you how to edit the file in your cPanel, but not how it should be changed. (You may have to look at other articles and resources to find this information.)
There are many ways to edit the .htaccess file
- Edit the file on your computer and upload it to the server via FTP
- Using Edit Mode in an FTP program
- Use an SSH Text editor
- Use the File Manager in cPanel
For most people, the easiest way to edit an .htaccess file is through the File Manager in cPanel.

Before anything else, we suggest that you make a backup of your website. This way, if any failure occurs, you can revert to a previous version of the file.

How to modify file and directory permissions
The permissions of a file or directory tell the server how and in what way it should interact with a file or directory.
This section will show you how to edit file permissions through cPanel, but not how you should modify them. (See our Is there anything I can do? section for more information).
