For seeing this quite often these days, here's how to fix it (most of the times).

 

You get an error like

We are sorry, but a MySQL - error occurred. The administrator may find more information in syslog with the ID 2e110e14094d8ad886efa2b14105632e

 

Checking the syslog, you might find something similar to this:

Froxlor: MySQL - Error: Establishing connection failed, exiting; ErrNo: 0; Desc: ; Script: /froxlor/customer_mysql.php?page=mysqls&s=xyz; Ref: ...

 

Removing the error-supressing from mysql_connect it will show the following, hopefully helpful message:

 

Warning: mysql_connect() [function.mysql-connect]: Premature end of data (mysqlnd_wireprotocol.c:553) in /var/www/froxlor/lib/classes/database/class.db.php on line 105

 

Warning: mysql_connect() [function.mysql-connect]: OK packet 1 bytes shorter than expected in /var/www/froxlor/lib/classes/database/class.db.php on line 105

 

Warning: mysql_connect() [function.mysql-connect]: mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file

 

I hope this will save some of you from getting a heart-attack
