Hi, I have the pro version of Formidable (http://formidablepro.com/) and installed it on my WP 5.1 installation. I noticed that when i do ‘Add New Form’ i get a blank page with only the header. The only way to create a form is via Templates. Formidable asked me to disable the template (http://themeforest.net/item/kallyas-responsive-multipurpose-wordpress-theme/4091658). And i do get the full page to add a form. Thus it seems that there is a confict.
What could be the problem? And can you check if there is a workaround?
