I’m getting a lot of 403 errors when doing anything - replying to posts, changing settings etc. This happened right after adding a bit of JS to the header, so I’m trying to remove it as step 1. Problem is, the errors prevent me from saving the changed header.

So that I can delete it manually, where are site customizations like this kept?
