== 500 Internal Server Error ==

The 500 internal server error indicates there is a problem processing the request. This is usually due to a customisation or an issue with the PHP configuration causing issues.

The first step would be to try and get further details on the error being raised. You can do this by adding <tt>$display_errors = true;</tt> to your <tt>configuration.php</tt> file or reviewing the PHP <tt>error_log</tt> file.

This should indicate which file is causing the error. If it is a 3rd party module or customization then you should remove the custom files and confirm if this resolves the error.

== Maximum Execution Time ==

By default, WHMCS enforces a max_execution_time limit of 300 seconds for general requests.

If this limit is too little for a given task or operation, you may encounter an error message that looks something like the following

<div class="source-cli">
PHP Fatal error: Maximum execution time of 300 seconds exceeded in /path/to/file.php
</div>

===Increasing the max_execution_time===

If you wish to override the max execution time limit and increase it to a higher value, you can do so by adding the following line to your WHMCS configuration.php file:

<div class="source-cli">
$overidephptimelimit = 500;
</div>
