Yesterday I have applied some of Defender's recommeded settings and website seemed OK. I have also used Hummingbirds script allocation/moving function to try to improve load time. I believe I moved JetPack scripts as part of it. Yesterday everything seemed ok, but today when session expired, I cannot login into the website any more. Neither Wordfence login with text message authentication nor WP (JetPack) login are not working. It hangs for a while and then throws the 500 error Internal Server Error

Apache Server at riverdentistry.com Port 80.
How do I revert/undo changes or disable plugins to be able to login?
