Hi,

I installed the version 2.5 of j!MailAlerts, and the system said that the installation was correct.

When I go to the back-end, I received a message "ERROR 500" and the page is not show..

I activated the error messages, and the error is:

"
Notice: Use of undefined constant __DIR__ - assumed '__DIR__' in /var/www/portalweb/libraries/fof/include.php on line 24

Warning: require_once(__DIR__/autoloader/fof.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/portalweb/libraries/fof/include.php on line 24

Fatal error: require_once() [function.require]: Failed opening required '__DIR__/autoloader/fof.php' (include_path='.:/usr/share/php:/usr/share/pear') in/var/www/portalweb/libraries/fof/include.php on line 24
"

I use Joomla 2.5

Any idea??

Thanks a lot.!!
