Config:
Joomla: Joomla! 1.5.9 Production/Stable [ Vatani [eCommerce Bundle] ] 9-January-2009 23:00 GMT
VirtueMart: 1.1.2
SEF: 3.2.11
VirtueMart (extension): 2.0.1

A couple of things.

The first one I found a work around for. When adding a product to your cart, the cart module should do a Ajax type update where the desired item is added. The script is triggered and runs.. but instead of updating the cart, a 404 message is displayed in the cart instead. The error I come to find is that it can't seem to find index2.php in the project root.

Workaround: In the JoomSef configuration change 404 Page : Show Page to "Front Page" instead of the default "404 page".

My second issue, which has caused quite the headache, occurs during checkout. When trying to go from the "Cart" page to "Checkout", instead of being presented with the Ajax type login prompt, it drops me back to the Virtuemart root page. (displays the product categories and icons).

If I disable SEF urls in the global config, everything works fine.

I couldn't say when exactly this started to occur.

Any idea of a workaround or a patch? Has anyone run into this before?
~~~~~~~~~~~~~~~~EDIT~~~~~~~~~~~~~~~~~~~~~
Got it. I remember this one from before now..
I set: Set server QUERY_STRING? to "yes", which fixed it.
Just for reference, what does this do on the backend? (Other than fix this problem)


Whoaaa. the forum is acting up too.... com'on guys, get it together.

Set QUERY_STRING yes, will overwrite the intial value PHP gets from webserver by the values parsed out from the original non-SEO DB stored in JoomSEF table in database.

In 99% cases, this should have no negative effects, however, there might be components relying on the original appearance of the QUERY_STRING value, which may be then "confused" by such behaviour.

However, we made this setting ON by default in the latest versions of JoomSEF.
