Unable to log in.
Installation and Configuration
There is an error. We need to figure out what that error is.
If you have firebug installed, you can open the console and see if there are any javascript errors there that give more indication of what the error is.
If you can FTP into the site, jamroom's error logs are at:
/data/logs
There might be an indication of what the error is in there.
Failing that,via FTP try renaming
/repair.php.html
to
/repair.php
then open it in a browser. That will run the integrity check.
You also might try deleting the contents of:
/data/cache/*
