Website requesting missing minified css/js files causes complete failure

Hello,

Thank you for your reply.
Sadly, I do not know how and why, but the website is broken even after deleting LS Cache plugin and restarting everything. Really frustrating. I am now downloading LS Cache 2.9.9.2 to test if this can fix the problem.

Hi,

Yes, I have disabled and deleted everything LSCWP related and still seeing the requests (I have hidden my domain/IP). This is in incognito mode with developers tools and cache disabled:

I have currently uploaded LSCWP 2.9.9.2, issued a ‘Empty Entire Cache’, restarted OLS and currently everything is back to normal.
I believe this was cached somewhere and it was cached badly. I made a dump of my database and searched for the filenames, but nothing found there. Any idea what could be causing it? I had this issue with 404 on one more website on another OLS server, but there disabling LSCWP fixed the issue.

Hi,

I have sent you the full request/response headers. This is after I have already disabled and deleted LSCWP 3.0.8.5.

For the sake of testing and finding what is causing this, I can once again update to 3.0.8.5 and see what happens if you want to.
Are you caching something new with the ‘domain key’ feature on your servers? Maybe this is the problem?

Hello,

I have installed 3.0.8.5 and managed to break it again. I think this is connected with browser cache and custom headers. I have deleted all custom headers, then purged cache and now seeing 404 errors again.

As you suggested, even after deactivating LSCWP, I still get x-litespeed-cache: hit header. Why is this and how can I fix it?

EDIT:

I have again added custom headers as advised here: https://openlitespeed.org/kb/how-to-set-up-custom-headers/ but using wp-content/litespeed/cssjs/ as URI.
This did not fix the problem. The only thing that fixed it was to again install version 2.9.9.2 and purge caches from there. I believe v3.0.8.5 is not clearing some caches properly on OLS, even after the plugin is deleted.
