Hello.

I did something. I don't know what, but I can't use my forum.
The server encountered an internal error or misconfiguration and was unable to complete your request.
This is error I received or that I can't access file index.php.

What should I do? I don't want to lose everything!

My www is: http://serials-fanatic.pl

Do you have a .htaccess file in your root folder?? Try renaming it to htaccess.txt and see if it works then.

Yes, I have. I renamed it and now I have error:
You don't have permission to access /index.php on this server.

Check your server error logs for more information. There must be something misconfigured somewhere if these are giving 403s with no .htaccess.

How to do that? What chmod should index.php have?

chmod 644

Your server error logs should be available in your host control panel somewhere, ask your host if you're not sure where it is.
