Hi - I've had a search around for an answer but can't find one that specifically addresses my issue!
I have several Lists in a 2013 SP site and one of them has the "Nintex Forms" icon greyed out (in the "Customize List" part of the ribbon).
I have checked the List Type and it is 120 - Custom grid and not 100 - general. I'm thinking this may be why. The list has a lot of data and calculated columns in it. If this is the reason, is there any way to change the list type?
