I too spent a group of time working to setup my site with this software. I originally thought it was great. Then, suddenly it just stopped working. The SEO input stayed, but not after I turned the Extention off.
I tried on multiple occasions to contact JJExtentions for support, but they have NO SUPPORT on there site. All I could find was an email drop down on their Menu under Contact.
If you need SEO simplification. This is NOT THE ANSWER!!!
