V. 1.6 Database Issue
I am not really sure if this is because of the 1.6 upgrade, but I lost all the data on one of my coupon sites shortly after the upgrade. It seems like my database got corrupted. I was with bluehost for 2+ hours and they told me that the upgrade could be the reasons. I am just reporting this in case others had the same issue. It is probably safer not to upgrade to 1.6 at this point.
