The first call is the one. The second is WordPress.

As per the link I posted, I need to see the response, not the request. This may show what is throwing a 404. It’s unlikely to be coming from Loco Translate, because the plugin won’t fail this way if there’s a problem.

As a side note the request you’ve posted is truncated. Did you do that deliberately?

Yes I cut it on purpose it was just dictionary data.

Here is the response:

Also this is what is dumped in console, when i hit Save button

Looks like the moderators have removed your post contents.

Regardless, I can see that the response is a HTML not found page. My plugin would not create such a response from an Ajax request. It will always return JSON unless something external is stopping it from working. I cannot guess at what that is in your case.

Yes looks like my posts were removed. To answer your first question, yes i truncated that because it was just raw data. So here is the console dump on gist
I disabled all plugins except Loco Translate
https://gist.github.com/struxoje/e7b4a589875662cabeae604367e4b6f3

I will send full response in a min

Here it is the response.It is as you said just 404 page. However, I have this problem only if I try to edit theme, however, if i do the same with plugins everything works perfectly. This is new installation, so there is nothing fancy in there and plugins are disabled

https://gist.github.com/struxoje/b3fa041aa3fa347cb0c11dc49af3646a

Btw in previous console dump there was
Provide the following text when reporting a problem:
–8<–

In case that means something to you

Thank you!

With debugging enabled I see in console:

These notices are not related to Loco Translate. I can’t say if they’re related to your 404. My guess would be not.

Your dumps confirm what we already know. Something is throwing a 404 at the admin-ajax.php end point. This should never result in a 404, and Loco Translate will never throw one.

My plugin relies on WordPress’s Ajax hooks to work properly. Something seems to be stopping them from working and I have no clue as to what it could be. The exact same issue has been reported dozens of times and I’ve never been able to reproduce the issue.

Ok thank you. Bad luck I guess :/ It’s strange as it’s clean install… I’ll try to put few outputs in admin-ajax.php, and see if i can get anywhere

And… I have a SOLUTION!

Finally ?? So, long story short it looks like mod_security is causing problems with some of the ajax calls, my hosting provider is namecheap, and they have mod_sec on by default, I tried to disable it via .htaccess editing but that didn’t help. Only way how to handle this was to contact support, they have been able to confirm that mod_sec rules have been triggered, and they whitelisted problematic rules. That solved the problem. I hope this will be helpful to other people who see similar issue. I would also like to thank you for help with this which helped me pin point the problem. Perhaps config option would be not to use ajax, in case people are facing problems.

Good news, thanks for posting back.

It would be useful if you could post the offending rules that caused the problem. That way I could at least add some kind of test / diagnostics screen to help people in future.

Disabling Ajax is an option I’d rather not go down. It’s a perfectly valid and common use of WordPress. However, I can see the value in reducing support time. I will look into how difficult it will be.

Unfortunately they didn’t give me any specifics on what problematic rules were ??

Unfortunately, this has happened to me as well, so it does not save po and mo files.

This is the Loco translate messege when i save it:
Error: Page not found | Fül?pgumi. Check console output for debugging information

Here is the console
