So, what happened then? Just interested . . .
I looked at the site after the email and found that one of the main php files had been cleared of its contents along with its backup.
I called LarryS and caught him as he was loading his car to go on week long trip.
He called me back after he got the site back up and stated that it appeared the site had been hacked.
He had to restore the site using a backup from the previous day.
When he gets back he's going to walk me through the steps to be able to do the restore via his service provider.
That's in case he is out of town and it happens again.
Why would someone hack a site like IWB? If it was for fun, they must have nothing better to do. Anyway, thank you to the two Larries for their prompt attention
