Hello MyBB forums,
Everything on my forums has been going well until today where trying to change certain settings on the Admin CP stopped working and a few hours later the threads also simply stopped working, instead they both give a 404 error instead of doing what they should.

Any help is appreciated.
Thank you.

Update: The solution was setting "Enable search engine friendly URLs?" back to "Automatic Detection" on "Server and Optimization Options".
