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.

Hello,

Anyway, we probably identified the problem, so we will release the new extension version very soon.

Hello,
new VirtueMart JoomSEF extension - version 2.0.18 is available. It addresses this issue also, please upgrade.
