For those that are experiencing the SQL error after installing the plugin-patch posted can you tell me what version of vBSEO you are using?
In looking at oly51's information he was running vBEO 3.2 which has a problem in one of its plugins that prevents a vBulletin variable (userinfo) from being shared with postbit plugins. This is an issue I identified some time ago and worked with the vBSEO team to resolve.
Here is a description of the problem and how to resolve it if you are using versions of vBSEO earlier than 3.3.0 Gold. Please note that the issue was fixed in 3.3.0 Gold but exists in all 3.3.0 release candidates and previous versions.
Best regards,
Mark
