Registered Access error

Ivan,
After installing my project in th production server (windows and PHP 5.3) I noticed a problem with Register User component.

If you mistake a user login or password, isted of show a error mesage, the site is returning this errors:

from IE8 or IE9:
HTTP 500 Internal server error

What did I do wrong after recovering the instalation? I used Akkeba kickstart process.

Ivan, just in case, see attached the image of the original error message we had from my development domain (.COM).

After upload using Akkeba Backup and kickstart to that .COM.BR domain (windows server), I noticed the issue described in this topic.

This saturday (14th) the environment .COM will be deleted... i don't know exacly what time, but you can try to check it with your admin user as well.

I did the kickstart installation (form akeeba backup) process again, and solved the issue.
