First, when I upgraded I got the line 75 error message. That was fixed by deactivating and reactivating. Shouldn't have to do that.
Now the contact form just doesn't show up now. I get about half the screen greyed out with the overlay and just a small square for the modal window. Basically its completely broken.
Not trying to sound harsh, but these are issues that should have been tested, noticed and addressed before publishing a release.
Hopefully there will be a fix soon. Really like this plugin.
