Hi again ramonjosegn,
He'd tested again the plugin on Firefox (and Chrome) with the listed plugins that you had sent us plus the top40 used plugins and we'd no luck to have the plugin in a non-working state.
The last thing that we can do is, if you feel comfortable, to login to your WordPress admin and check what's going on.
If you are ok with that, can you contact us: support@sitecops.com with a temp admin username, password and URL of your site, so that we can debug your specific site situation.
PS: For now, we are marking this as resolved, since from our tests it should be working just fine in the general case.
Thanks,
SiteCops Team
