Well if you never enabled the mysql error logs in ubb,you will get that generic message but no detail files to view in the folder it would be stored in.
If there are any helpful details.
There is a cheat however to see if it is reporting anything specific.
Edit libs/mysql.inc.php.
search for $showerror=0
change that value to 1.
if there is any additional errors reported it will appear in the browser.
Just note though when done change it back to 0.
because all users will see the details.
