Hello,
I have already reported this problem. One of pages in my project called 'View List' has a lot of html elements and seem to be problematic for Appery Editor. I was unable to open it, but found a workaround. When I opened less complex page first and then the problematic one I could acces it. It usually took like 3-5 min - annoying but bearable. For some reason now my trick does not work anymore. Page loads forever. I waited like ONE HOUR without success
Please help, I am finishing my project, this page is essential for it.
