Looks like you have the original version of the cMap template installed, which is three to four years old. A lot of support for legacy templates was removed in the 0.8.x version of Connections while still retaining as much backward compatibility as possible. I didn’t test compatibility all the way to back to the original versions of cMap because most site have updated or moved on or do not exist anymore.
The two options are to update the cMap template or to rollback Connections to 0.7.9.7.
I did a search of the purchase history using your email address and I could not find a record, so perhaps you purchased cMap using a different email address? If you know the email address that cMap was purchased under, you can access the update from your purchase history page.
I hope that helps!
