I got this error message this morning. The first time I was trying to import a constituent and an organization relationship at the same time, so when I got the error message figured that there was something I hadn't set up correctly in the Profile. Instead of spending time trying to figure that out, I decided to just do a straight constituent import, nothing but name and address fields, importing into batch, and add the relationship later. But I got this same message! When the error message appears, it has 2 options, See Details and Continue. The former gives you instructions on how to set up jit debugging, I'd really rather not go there unless that's the only way. When I click Continue, nothing happens, the Import screen is just frozen and there is no batch. I did upgrade to 1.7.4 yesterday, and used IOM to do our standard lockbox gift import, and everything was fine. Please help!
