I have been using Concrete5 for a couple years. I decided to move a site from ipage to arvixe and decided to try 5.7. It looks good. I can get to the site. I can click on edit page and it turns green, and then I cannot access any block on the page.

I am using the element template. I tried changing themes, but that has no effect. I don't have any other addons.

At the bottom of each page it says it states: An unexpected error occurred. Module 'zip' already loaded

Arvixe cannot assist. Everything seems to be working on their end.
