I am running JoomSEF: version 3.5.4
with the Virtuemart extension: 2.0.16

the website is: www.socialthinking.com

Basically the issue I am having is the SEF URL for checkout doesn't work. The site reverts back to www.socialthinking.com when I am on the checkout process, and the Checkout progress links do not work correctly.

If I try to go back to step 2 - I get bumped back to Step 1 - no matter where in the process I am located.

What I have done so far to try and resolve this:
1. I have updated to the most current versions both from the updater and manual install.
2. I have disabled the SEF Cart URLs generator from the VM extension Config.
3. I have regenerated the URLs and Flushed the Cache.

None of these steps have resolved the issue at this time. Any help on getting this resolved would be really appreciated.

Any word on a fix for this?

I have the a similar issue with browsing categories. the pagination doesn't advance at all. I see multiple posts on the Artio forum about this and other pagination issues. but I dont see a thread or comment by Artio with a fix or suggestions.

I have upgraded everything on my site Joomla, VM, artio and it still doesnt work. I hope it gets resolved soon.
