Everything was working correctly but then the following error occurred:
Failed... Reason: Can't connect to local MySQL server through socket '/tmp/mysql.sock'
Answer:
The above error means that the mysql server has stopped. For things to work again the MySQL server needs to be started as the server stopped running.
If this is not your own server then you will need to contact your hosting company and explain to them that the MySQL server is not running anymore and that it has to be started for your scripts to be able to make use of the MySQL database. You could also forward them the URL of this Knowledge Base entry for an explanation of the problem.
