Hello all-

I've been busily plugging away at zen cart for a few weeks now and have been managing but now I have what seems like a huge problem.

I downloaded and installed the Newsletter-Only add-on for 1.3.9 (not an upgrade) and moved the folders based on the category tree. Something must not have been in the correct place for my folders because the admin screen went blank and I couldn't access it at all. I moved some things around and then the admin came back with the option to install. I did that and then went to tools/layout boxes. All the settings are gone from the list. It looks like it is pulling from the wrong file. All of the menu items that were previously there, like products and options for featured items, specials, etc are no longer there. Does anyone know how to fix this?

I have removed all the files for the add-on and uploaded the back up files that were overwritten.

Any help would be greatly appreciated. Thank you.
