M-ai facut curios, iar la mine acum afiseaza aceeasi eroare despre care am scris in primul mesaj (care dupa ce am vazut-o prima data nu a mai aparut). Aceasta este:

Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/dirpedia/public_html/app/models/MySQL.php on line 7
Fatal error: MySQL connection failed.
Deci clar este vorba de o problema.
