Lee found the proverbial needle in the haystack with a problem I had and fixed it! He was in contact everyday until he ruled out all other possibilities and today my site is back to SEF URL's!
Thanks again Lee, I wouldn't hesitate to purchase this extension again. :o)
BUT... I have one minor problem in that it is conflicting with my front page slideshow (from Joomla Bamboo)and there appears to be ZERO support for it. Someone else on their forum had the same problem in April 2009 and they're still waiting for an answer!!
Unbelievably disappointed because now I agree with the other reviews about lack of support, I was hoping I wouldn't have the same issues...
