I installed Links SQL 2.0 correctly 1 week ago. All looked correctly (connection to mysql database, posting new links...) but 2 days ago I tried to post new links and it appeared a database error:

Error: Could not connect to database. Reason: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)

I've been searching through this forum looking for an answer but I'm not root in my webserver and I can't run telnet to make the needed changes. Is there any other method?

It's very strange because it has could connect ever to MySQL database and I don't know why now it doesn't.
Host,database name,login and password are correct.

I tell my hosting admin about my problem and said he made no changes on database and it goes correctly.


Please, help me!
