What to do if nothing is fixing the errors

I followed all steps but nothing is working, what can I do?

If you have followed all steps, then you just have a virus in your server. Try creating a clean server with only the default framework scripts and jaksam's scripts

How to verify if I have a virus in my server?

Open the file which is being mentioned by jaksam's script with notepad, scroll down to the bottom. If there is partially readable code (for example "local..."), that's a virus added by something else, because normally the entire file would be encrypted. In this case, you'll have to solve that issue before being able to use any script
