Debugging Modsec & Litespeed Server

Hello Everyone, I have a strange one here, I have setup a new WordPress site/Directory and all of a sudden I am getting 404 errors on css and image file loading on this particular website. So, I can only think either ModSec is blocking this file types (they are not being triggered in the main ModSecurity Control) or is it a Litespeed Server issue? I need to understand what is the best way to debug the file types being blocked by the server, how would I debug the ModSec for that specific site to see if it is that causing the issue? Thanks Rockforduk

  Hey there! The easiest option would be to just turn off ModSecurity temporarily, but it seems odd to me that it wouldn't be logging anything if that was indeed the software causing the issue. I would expect a 404 error to be logged somewhere, so before digging into ModSecurity too much I would try disabling Litespeed to see if that at least gets you an error message.

  These are the errors in Developer Tools

  Thanks for that, although that wouldn't show us the "why" behind why they are being displayed.
