“500 - An error has occurred” in Joomla, when attemping to login in backend

问题

When I attemp to login in the backend using the right login of the Super User i get an error page "500 - An error has occurred."

I have changed the Super User password by PhpMyAdmin and the error remains.

I have installed Joomla 2.5 installed.

First you have change folder permission to 775 for the following folders:

cache, logs, tmp & administrator/cache

Then go to: configuration.php

find code:
$log_path = 'XXXXXXXXXXXXX';
$tmp_path = 'XXXXXXXXXXXXX';

and change code into:
$log_path = './logs';
$tmp_path = './tmp';
