There was an error while saving your form. (Also can't import)

I'm running GF on a multisite. I've not had any problems with it on any of the other sites (and I use it on almost all of the 23 sites. I went to import a generic form I use to get started quickly creating contact forms, and it said it imported just fine, but when I click over to forms, there's none there, just the message telling me to create one. I then tried just creating it from scratch and go the "There was an error while saving your form. Please contact our support team." message. Please help.

I tried adding with just a single text line, and it gave the same error. The ones I'm trying to import are not very complex either. Basically just name, email, phone, subject, message, and they're all required, nothing fancy at all.

Well I'll have to assume it's a theme conflict, because all the same plugins are running on other sites on the multisite without issue. Any idea what kinds of things I should look for in my theme that would cause a conflict?

Okay, I've switched to the Twenty-Eleven theme, and no luck. Still can't save. I turned off the 2 plugins that were individually activated on that site, but I can't turn off the network-activated plugins and remove functionality from all my other sites. However, all the other sites are running those same network-activated plugins and Gravity Forms, without any problems.

I've sent you an invite to add your account to the site. You'll be an admin on the one that's having the issue: NFT Academy. The email will be from FiddlerSites.com or FiddlerStudios. Once you're in, let me know and I can make you a super-admin, if you need to see themes, or compare to other sites, etc. Thanks.
