AbleCommerce Shopping Cart Software

I searched the forums and found another person who was getting this error. I wanted to make sure this is the solution as I was unclear. I get the following error when almost done with the upgrade...

Server Error in '/' Application.

Source Error:

Line 158: {
Line 159: //VALIDATE DATA IN SHIPZONES
Line 160: _ShipZones = ShipZoneDataSource.LoadForStore();
Line 161: foreach (ShipZone zone in _ShipZones)
Line 162: {

Is this the solution?

With 7.0.2 install package there is a file named web_NET35.config. Rename it to web.config and replace your old web.config file with this one.

Thank you.

That shouldn't be the problem-- the switch to 3.5 was optional. It sounds more like a database access issue. The fields in the ac_ShipZones table changed between the builds. The one in 7.0.2 has more fields.

Make sure that that there is not pending database upgrade script.
