Tihana, I downloaded the latest Breezing Forms version, unzipped it, and dragged in "com_breezingforms.zip" from the "extensions" folder.
It installed without errors.
But, I'm still seeing that weird screen I originally posted and can't work on any existing forms.
FYI, I'm using Chrome Version 93.0.4577.63 (Official Build) (64-bit).
And I just tried it using Firefox and Breezing Forms is working fine!
So, something is up with Chrome. Are there any Chrome settings you know about that could be causing this? I'd rather use Chrome...
Thanks!
