admin-ajax (403) issue WordPress

when logged as admin admin-ajax.php working fine. if non-authenticated user access admin-ajax.php return 403. I tried the following operation:

  • file permission changed
  • all the plugin uninstalled and installed.
  • .htaccess file regenerated.

The issue still not fixed. Does any other possibility fix these issues? where I found the uwf firewall access log?

Hi @bobbyiliev,

Thanks for your update. I have didn’t install any cache related plugin and security related plugin.

Thanks, Mani


I’ve had a similar problem in the past and it was because of a caching plugin like W3 Total cache or similar. Basically minified JavaScript files could be causing the issue.

What I could suggest is to purge the cache and check for the permissions applied to cached files as well. Note that disabling the W3 total cache plugin does not delete the cached files.

Let me know how it goes! Regards, Bobby
