Here I am, two weeks later, same problem exists, from just this one computer. Nothing that anyone has suggested makes the slightest bit of difference. I even went so far as to dump all history, cookies, forms, etc, recover the computer to a point before all this happened, changed browsers to FireFox, and still, everythime I try to get into the Forum, the error comes up:
The database value you're trying to insert does not exist: latitude
I realize that you can't deal with the specifics of someones Forum just because they use Simple machine, but since this problem seems to be with MY computer, as a simple subscriber, it seems to me that the problem certainly must have occurred before. All I want is to sign in to the damn Forum.
I'm in Arizona, not using a proxie, and have my IP from Cox. This problem just started out of the clear blue sky two weeks ago - and happens from no other computer, nor does it happen when I access via iPAD.
