Colibi stuck on loading

I hope someone could help me with this issue. I am using colibri page builder and trying to edit my front page and all it does is say loading please wait… I have deactivated all plugins except colibri and it still does the same thing. I have reached out to there support but they are very slow at replying back. Any help would be much appreciated. If I edit other pages aside from my main page it loads right up
