Error : mysql_query(): Can't connect to local MySQL server through socket '/tmp/mysqld.sock' (2)

Hi there,

after some problems to log in at the backend I updated to Evo1.2.1.
Now I can login at the backend an everything looks fine as far as I can say, but if I call the site, I get the following Error:

Someone there who knows the issue and can solve this?

I would say you have a snippet or plugin which has mysql_ function when it should really be $modx->db->getRow().

Without more info it would be difficult to say where. If you can get to the manager do you have an event logged for it?
