Invision Community 4: SEO, prepare for v5 and dormant account notifications By Matt Monday at 02:04 PM
kstan Posted January 22, 2023 Posted January 22, 2023 When I click the "Edit HTML and CSS" button for a theme (any theme) I get an "Internal server error". I have tried to look for information in the error log for the server, but I can't find anything. I also tried to downgrade to PHP 8 from PHP 8.1, but that makes the whole site fail. I also tried to disable plugins to no avail. I have no idea what to do next.
Nathan Explosion Posted January 22, 2023 Posted January 22, 2023 Check if you have mod_security enabled, and disable it if so. kstan 1
kstan Posted January 22, 2023 Author Posted January 22, 2023 Would that be in the conf_global file? Is so, I do not.

Well, I am my own hosting provider (although I don't really know what I'm doing), and I did in fact have ModSecurity installed. It seemed like a difficult and risky task to just turn it off altogether, so instead I experimented with turning certain features off, and lo and behold, turning off "Backend Compression" did the trick! Thank you for saving me!
