I have the paid JoomSEF with the Virtuemart extension. When I enable SEF support in the Joomla! global configuration, clicking on the checkout button or on the items in the cart yields a 404 error. If I disable SEF support, it works fine.

i have SEF v3.7.1 and v2.0.30 of the JSEF VM extension

Hello,

Go to JoomSEF's configuration and on the Advanced tab try setting the "Set page base href value" option to "No - disable base href generation".
If that doesn't help, what kind of 404 error is displayed? The default browser 404 page, or the 404 Not found page in the Joomla's template? Could you post a link to your website where I can see the problem myself?

Best regards,

Sorry for jumping in, but I've got the same problem. I've tried the following possible solutions:
- set "server query string" tot "yes",
- set "sef checkout urls" to "no" in "manage extensions-VirtueMart",
- set "page base href value" to "no".
The 404-page displayed is the default browser-404-page.

Joomla 1.5.22 (in general config all 3 sef-settings are set to "yes")
VirtueMart 1.1.6
JoomSEF 3.7.6 (JoomSef3-VM-bundle, see nr: 14406)

When JoomSef is disabled, the checkout-redirect works good, but with JoomSef enabled, you'll get the default browser-404-page, see: www.wolkewietjespeelgoed.nl

PS: Could it be there's a piece missing in the url? When i put "cart" into the url like: www.wolkewietjespeelgoed.nl/cart?page=ch...cted=1&Itemid=15
I get to see the right page...

Please, could anyone help me with this? The website where this problem shows up is an existing webshop of one of my clients, so we really want this to work good!
Thanks in advance.

Once again, I spent several hours trying all sorts of things I knew allready and could find about these kind of problems. No luck so far, but I'm sure it has nothing to do with other templates (said in some comments on the forum) and I'm sure it hás to do with the JoomSef-bundle, because everything works fine when JoomSef is deactivated.
This makes me wonder whether it has to do with the part missing in the url (see former post above) and how to make this working, or whether this has to do with the VM-1.1.6-version, since there's nothing about this combi on the internet yet.

Since I'm not getting any reply on this forum or at the email I've sent, I want my money back. The site this problem shows on, is a live webshop and I can't make my clients wait any longer; they really need this working! I'm very sorry, I had expected a bit more support when paying for this JoomSef-VM-bundle...
