Hello Makers, 👋

This guide will help you to troubleshoot the "Maximum execution time exceeded (Error 504)" error on your CMS-based website.


Insufficient PHP max_execution_time value. You just need to increase this value on your Plesk control panel.


  • Login to your Plesk control panel

  • Select PHP Settings under your domain

  • On the next page, you can choose the execution time in the dropdown or enter the custom value (click on a value field to set a custom value), based on your needs, and don't forget to save the changes!

And that's it! You've increased the max_execution_time and now you just need to clear your site cache.

Happy Making!
