How to increase PHP memory limit on a WP setup?

I’m trying to figure out why a certain plugin (Elementor) isn’t working. The widget panel doesn’t stop loading (loading icon doesn’t stop spinning) and after looking it up and trying the various methods they suggest, I’m left at where I started. My php memory limit is currently set to 128mb and I think I’m supposed to increase that to 512mb but the suggestions they gave me didn’t work. Is there anything else I can do? Do I have to increase my droplet size?

I ended up figuring out the issue. I isolated the issue by turning off all other plugins, etc. and found out it was the theme’s core plugin that wasn’t interacting well with Elementor. I upgraded the core plugin and all is well now.

Hello @keebs82

I’ve had similar issues with the Elementor plugin. You can examine the php_error_log and you should see references about exceeded PHP memory limit. In my case, I needed to increase the PHP memory limit as the value was set to a default value which was rather low.

The thing is there might be another plugin that is causing the issue here. The Apache/Nginx error_log should also shed more light.


Hi there,

What I could suggest is:

  • Try enabling WordPress debug mode so that you could get more errors and possibly point you to the right direction
  • Look in your PHP error logs for some errors that might be causing that problem
  • Check your web browser console for any JavaScript errors

Feel free to share any of the errors here so we could try to advise you further.

Increasing the size of your Droplet is also an option, but it is better to first get the actual error that is causing the problem.

Let me know how it goes!
