Last post by stawebnice - February 26, 2026, 19:23:58 PM
Hi Max,

please could you help me?

I'm trying to update VM on Joomla 4.4.10 (PHP 8.1) to 4.6.0 (tried the same with 4.6.2 and 4.6.4) but when I do it, I get this error:

Undefined constant "VMPATH_ADMINISTRATOR" and the whole admin of Joomla is blocked by this,


I can't get anywhere, even to install it again (which is what shows as recommendation when I install it firt)

Do you have any tip how to fix this?

Thank you!

Peta

3rd party extension / Re: Mollie for VirtueMart
Last post by vmfyelloq19 - February 25, 2026, 16:03:00 PM
One month now, no answer to support ticket at iStraxx / Virtuemart, no reaction from NorrNext here. Very disappointing.

NortNext seems to be a scam company, would not recommend buying from them.

About VirtueMart - not for support posts / New e-commerce website with VM...
Last post by Darko F. - February 25, 2026, 09:38:40 AM
So after a while I get client request to create for him a e-commerce website.

I already create few q years ago with Virtue Mart as Max well know since constantly bothering  him  :D

I like VMart because versatility but
before I proceed with Virtue Mart to decide if is worth here is questions.

What's status for J6 and extension for?

Is for J5 bug free?

Are extension for new VM stripe paypal klarna and other popular native or we need to pay third party development.

Are shipping extensions available apart default basic ones. I know old one calculate by rules don't work anymore at last it didn't years ago maybe someon upgraded it.

Is search for VM worth it. Old one was rubbish I need to go third party elastic search and home server. Is a unnecessary hustle.

So basically please give me hones opinion is Virtue Mart still relevant today?

And please after reading my post, don't think I don't want pay third party developers. I buy a lot from them in past, but reality today that competition offer this.
And since VirtueMart is now subscription based I don't expect any les from him

Thank you all God bless 😊

Last post by umbcel - February 22, 2026, 17:33:39 PM
Hi,
I had this problem that was driving me crazy, even though I had followed all the instructions and set up VM correctly.

So I decided to take the hard route, modifying the code and creating an override for the affected file.
I created the override in the HTML folder of my site template (Yootheme Pro 5).

In this folder, I created the following folder and subfolder structure:
  com_virtuemart
         |_____ sublayouts
I then copied the bs5-products.php file from mywebsitepath\\components\com_virtuemart\sublayouts into the newly created sublayouts subfolder.
I then modified the code as follows:

Line 83:
Code Select
<a title="<?php echo $product->product_name ?>" href="<?php echo JRoute::_('index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $product->virtuemart_product_id . '&virtuemart_category_id=' . $product->virtuemart_category_id); ?>">
Line 107:
Code Select
<h2 class="vm-product-title text-center pb-2 mb-0"><?php echo HTMLHelper::link (JRoute::_('index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $product->virtuemart_product_id . '&virtuemart_category_id=' . $product->virtuemart_category_id), $product->product_name); ?></h2>
Line 124:
Code Select
<a class="btn btn-secondary w-100 mt-3" href="<?php echo JRoute::_('index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=' . $product->virtuemart_product_id . '&virtuemart_category_id=' . $product->virtuemart_category_id); ?>" title="<?php echo $product->product_name; ?>"><?php echo vmText::_ ( 'COM_VIRTUEMART_PRODUCT_DETAILS' ); ?></a>
I don't know if this is the best way to fix the problem, but everything works perfectly now.

I hope this can help other people who are going crazy with the same problem I had.
