We've been told the "Load More Topics" button hangs and doesn't load new posts. The user that reported this just seeing the spinner leading more posts, but nothing loads. I was able to replicate the issue but after rebuilding the threads, cleared the forum cache, and virtually everything else it works. This user is on a PC with Microsoft Edge. I have a Mac and downloaded Edge and haven't been able to replicate. Maybe a Windows issue? Any ideas of how to fix this would be great. Thanks in advance for your help!

It doesn't work because there is an ISSUE:

 

XHR POST https://forums.fiskerati.com/wp-admin/admin-ajax.php?lang=en

[HTTP/2 403 Forbidden 62ms]

@seancallahan,

The AJAX requests are blocked by some security or cache plugin. It seems you've played with cache and security of your website and stopped all essential features of WordPress. You should not block admin-ajax.php requests.

Here is the screenshot of your problem:

@robert It doesn't look blocked when you go to https://forums.fiskerati.com/wp-admin/admin-ajax.php ?? That would typically throw a 403 or 503 page. Wouldn't it? Have any ideas to troubleshoot this?

No, it shouldn't return 403 normally. Just an empty page.

PRESS f12 and see the issue in your browser console. Your security plugin or something is blocking that.

Do what @robert suggested. There is no other way.

@robert I disabled Cloudflare page caching. Does that make the file(s) load on your screen. I don't see any network errors on my browser. Could you please confirm?

It doesn't load. Not a caching issue apparently. Cache plugins do not 403 anything.

@dimalifragis This is what I see, shows "Status: 200 OK" on both Chrome and Safari for me. See screenshot. Do you get this after refreshing the browser or still the same issue?

Trust me, the issue is there. This is my daily job for the last 10 years.

BUT checking your issue with Chrome (i was with Firefox before), i see some more details that might help you.

Seems to me like an OPTIMIZER issue. And looking at your source, your page IS optimized.

@dimalifragis Thank you! I did have an "Optimizer" which I have just deactivated and uninstalled. Did this resolve the issue you see?

This is a security configuration issue, so disabling the optimizer plugins will not help.

The security plugins add new lines in .htaccess files in different directories, so even if you disable them, the .htaccess files may still be there and stop ajax requests. It's better to ask your hosting support and let them find why your WordPress ajax requests are blocked.
