My website was working without any problems until ~8 pm this evening. When I wanted to access it, it was showing a database error. I thought it's just a temporary problem, but it was not going away. I checked my config file (yes, I'm on WP), and its info was not 100% correct. I fixed it and the website was working once again. However...the text editor was gone, the preview button won't show any changes, there are problems with picture uploads, the text won't show when you are typing it and much more. I fixed the text editor problem by installing a custom editor plugin, but there are still some of the problems, which I have no idea how to fix (could anyone help, by the way?) Is there any chance I was hacked? If yes, how could I protect myself? I changed my info, both my hosting/ftp info and my website login info. Thanks!
