Bah, I seem to of hit a nerve. I ment no disrespect to anyone, my original point was why add or modify something systemwide with out testing it in house.
Frankly, I'm a beginner at this stuff. I plan on starting college this fall for IT. What I know (html, php, mySQLwise) I've pretty much picked on up on various how to sites, forums much like this and trial & error.
The site I referenced with the mySQL error is http://www.weddingdayblues.com Its a vBulletin forum, still in the rough I haven't done much promoting yet because I want to get things just right. At any rate any time there is a db error, vB sends me an email. I really don't know what all of them mean so I go check the site and if things seem to be working I delete the email.
Again I didn't mean to ruffle anyone's feathers just making a point that things should be tested before going live. Just as I'm not advertising or promoting my site until I'm satisfied things are working correctly.
