I had this error occure in a site I am designing:
Column count doesn't match value count at row 1
I had never seen it be for so I first checked mysql.com and of course they give you mor complex error message to explain it. So next step phpbuilder.com but wait your search doesn't allow a search of that length. I guess I am just screwed.
Fortunatly someone at Google knows more about searching and I found the answer and guess were the answer was, just guess.
I would recommend making your sites search a little more freindly, it would definately reduce the number of posts. You need to let people search for a complete error messages and you need to add "exact phrase" searching.
The answer was in your forum.
