While importing WordPress theme demo data or running a PHP script, a fatal error might occur because the maximum limitations were exceeded. For example, a PHP script can run for a maximum of 30 seconds by default. So, the system will give an error if the script is ran for more than 30 seconds. We should increase these limitations in certain circumstances in the functions.php and wp-config files by using the ini_set() method.
There are 2 parameters:
- setting_name: It specifies the name of the setting we need to modify.
- value: Assigns the value to the setting.
Increase the limitations in functions.php and wp-config files
Find the functions.php and wp-config files and add the following code and Update File.
@ini_set('max_input_time', '6000'); //300 seconds = 5 minutes
@ini_set('max_execution_time', '6000'); // for infinite time of execution
@ini_set('memory_limit', '128M');
@ini_set('post_max_size', '64M');
@ini_set('upload_max_filesize', '32M');
@set_time_limit(9999);
