Problem #

You see the following error message:

PHP Fatal error: Maximum execution time of 300 seconds exceeded in /path/to/file.php

Cause #

The max_execution_time limit is too low for a specific task or operation. By default, WHMCS enforces a max_execution_time limit of 300 seconds for general requests.

Solution #

Increase the max_execution_time limit by adding the following new line to your configuration.php file:

$overidephptimelimit = 500;
