MyBB Community Forums

Alright, so I've been working on my forums for a few weeks now, I'm using Filezilla FTP software and was editing some files in there. My mouse button became stuck, moved some files in the public.html folder around, and my forum seized to work, terrified I reset my filezilla connection hoping it would resolve the issue... It did not, and now I'm not sure how to fix it :|

Please, MyBB community, help me solve this problem.

Upload the root files, index.php, online.php, member.php, search.php, all the files in this area, and it should be OK.

Alright, I tried that, but now I get something along the lines of

SQL Error:
2003 - Can't connect to MySQL server on 'mysql7.000webhost.com' (111)
Query:
[READ] Unable to connect to MySQL server

Did you only upload the root files again?? If so you'll need to ask your host about that error.
