I can't login, register or any function that contain in file member.php. Can you help me?
My forum url: http://h-ours.net/

Download a fresh zip file from mybb.com and upload the member.php (or all files) again.

I tried, but It doesn't work

Can you access the error logs of your webserver?

Reuploading a file isn't going to solve this, you have 500 Internal Errors occuring, which could be anything. Check the server error logs and contact your host.

I found it, It's a fault when I change Registration Agreement in my language
