Hello, I just bought and installed the JoomSEF 2.1.1 com and already had the VM 1.0 ext.

When I install them on my site I get the error below:

Warning: extract() [function.extract]: First argument should be an array in /home/cyclenut/public_html/components/com_sef/sef_ext/com_virtuemart.php on line 17

Fatal error: Cannot instantiate non-existent class: sefext_com_virtuemart in /home/cyclenut/public_html/components/com_sef/joomsef.php on line 1

Any ideas?<br><br>Post edited by: tony@evolutioncomputersys, at: 2007/10/06 15:01

Dear Tony,

VM 1.0.0 will work only with JoomSEF 1.x and VM 1.1.0 will work with JoomSEF 2.x.
In a normal process, when you update from JoomSEF 1.x to JoomSEF 2.x you can also upgrade your extensions (such as that one for VM) automatically.

Somehow, the other way is not expected. :-)
So, we will send you the right VM extension version you need for your current JoomSEF version.

Best regards,

I installed the 1.1.2 version that you sent me and the site will not come up and I am getting the error below.

Fatal error: Class sefext_com_virtuemart: Cannot inherit from undefined class sef_joomsef in /home/cyclenut/public_html/components/com_sef/sef_ext/com_virtuemart.php on line 13

Hello Tony,

if you tried complete uninstall and reinstall of both the component and the extension then I really do not have any more ideas at the moment without checking the site in question.
We have JoomSEF 2.2.0 and VM Extension 1.1.2 installed at many sites and we have not experienced such problem anywhere.
It really seems to be a version conflict, but if you are sure about your versions, then I really cannot advice anything else without taking a look at the site.

If you want to grant us the access for short time only, we will do just a fast check and let you know about our findings.

Hello Tony,

thanks for the access info.

Well, we installed the JoomSEF 2.2.0 and VM Extension 1.1.2 and it seems to work fine.

Thanks for taking a look at it. I'm confused but happy as to why it's working when you did the exact same thing that I did.

The site must have been more afraid of you than me ;-)

Thanks again
