It's your MySQL version

See here for more info and Lynne from here caught that in the similar message posted just like yours.

You can contact your host and see if they have other servers that run a higher version of MySQL and if so see if they have PHP5 on it too. Read the rquirements that were stickied either last night or this morning... http://www.vbulletin.com/forum/showt...m-Requirements

You're having an old version of MySQL.

Minimum required MySQL version: 4.1 (Recommended is 5.0.19)
