Max Execution Time is the amount of time (in seconds) that your site will spend on a single operation before timing out (to avoid server lockups)
The max_execution_time directive can be set in
wp-config.php file. To gain access to these files you will need FTP credentials. If you do not have these please contact your hosting provider.
- In your WordPress root installation locate any of these
- Edit the file and paste the directive code
- Once you are done making changes save the file. If you have downloaded the file to make this change, upload it back to your server and override the existing file.
