WP PHP maximum execution time or PHP time limit is the amount of time in seconds that a website will spend on a single operation before timing out. This time is useful to avoid any potential server lockup. The default PHP time limit for WordPress is 40 seconds. When a certain operation reaches this execution time limit, the system will return the ‘Maximum execution time of X seconds exceeded‘ fatal error. 40 seconds may not be enough to install a complete demo for a theme or big plugin, thus it will be prudent to increase it so that your website can successfully complete the operation.
