Often times when executing a PHP script, you will run into an error related to a timeout.
This request takes too long to process, it is timed out by the server. If it should not be timed out, please contact administrator of this web site to increase 'Connection Timeout'.
1) Log into WHM
2) Navigate to "MultiPHP INI Editor"
3) Select the version of PHP that your site uses
4) Increase the following variables
-Max Execution Time
5) Click "Apply"
6) Repeat for all versions of PHP that are having a timeout error.
Depending on the error, you may need to increase the "max input time" directive from this same interface.
This directive sets the maximum time in seconds a script is allowed to parse input data, like POST, GET and file uploads.
