In Post Ad Issues

When using this plugin on a new site I notice the following:

1. The Ad URL doesn’t work so I end up adding the URL on the image via the text editor.

2. When trying to connect or link categories to ads the selections don’t stick. So if I link one ad to show only in categories 1,2,3, hit Save, the changes don’t take.

New site I just moved to it’s own db and multisite.

Any responses appreciated.
