Database Error (on upgrade to 2.3)

Hello All –

I am getting the following error when i save/publish a post or a page, and it happened after upgrading to 2.3. I am not sure if it is a line of PHP fix, or if a new database must be created. Your help is appreciated. Thanks. Scott

Here’s the error that gets generated:

PROBLEM:
********************************************************************
