Hi sikor79, and thanks for replying.
I figured it out, turns out it matters what order your plugins are in in the Sobi2 Plugin Manager. I moved my SEF Plugin to last in the list, and made the Gallery #1. After that, the entry edit form started working fine.
I moved it to another URL:
www.ishopprototype.com, take a look and see if there is anything you think this new Directory could use; we are creating potentially hundreds of these systems for each Florida city, then the SouthEast US, then... you get the idea.
