Same here!

I assume contact the dev of mod_sj_vm_extra_slider but unclear what is your current error and on what views u see it?

or see here -- the router has just been updated so maybe a re-install update ( I meant that) will help

not reinstall. We always update. The problem is in the 3rd party software not following the mega old advice how to include VM in your code.

But the new router has a kind of compatibility rearrangment. The new router includes the config and is checking if the config was already loaded.

I have 2 shops, both updated, but on different servers although same supplier.
One works, one doesn't.

Moved to a different server etc, and it still refused.
On a hunch, I downgraded to VM 3.6.2, and it all started working again. 

The "hunch":
In short: I have a test sub-domain on the working server. Since it is a test area, I hadn't upgraded it from the VM 3.6.2 version.
I added some pictures to a product, and all was good.
I then upgraded to the VM 3.6.4, and that's when it collapsed.
It was under the installation of the aio that it went bad.
So, a downgrade fixed that... and then I tested the same thing on the working site. Same thing happened.

I have a working live sub-domain on the same server etc, which IS updated to 3.6.4 and it works fine.
The test site has no 3-party stuff... it is a clean VM installation for testing purposes.

[Nilsy]

Sorry... I have 3.6.2 on the other site too! 

[EvanGR]

I had the same problem, with product pages, after I updated to the latest 3.6.x version... I had to rollback to 3.6.3.

(I also use breakdesigns extensions, not sure if this has anything to do with it)

[GJC Web Design]

the EXACT same error?

Which 3.6.6.xxxx - it matters

Post the trace please

[EvanGR]

Not sure if it was the EXACT same error.

But it was a "call to undefined vmdebug()" in single product pages. I know because I was looking for vmdebug() function calls in my template override, thinking it was my fault.

It must have been version 3.6.6.10187.
Rolled back to 3.6.3 10177 which works fine.

[GJC Web Design]

com_virtuemart.3.6.6.10191 improves the config loading to try and account for poorly coded 3rd party ext --

[EvanGR]

Thanks, I will try it, and report back.

[EvanGR]

Same disaster with latest v3.6.6.10191.

Now it's stuck and it's not rolling back to a previous working version... fingers crossed...

[Nilsy]

I tried VM3.6.6.10191 - not working for me.
I tried VM3.6.4.10187 - not working for me.
I tried VM3.6.3.10184 - not working for me.

Rolled back to VM3.6.2.10159, and things work again.

This is the fault list I get when I turn the debug on maximum (see attachment).

J.3.9.12
VM3.6.6.10191

I also had same issue with single product pages. Kept my VM3.6.6.10191 install, but rolled back /components/com_virtuemart/router.php to VM3.6.2.10159 and now working.

Where is the advise re '... old advice how to include VM in your code' ?

thanks
