Joomla 4 is stable with Virtuemart 4 ?

[tuaneric]

Hello

I have used Joomla 3.10 and Virtuemart 3.6 for my computer repair and spare parts store for 6 years, I hesitate to choose to update Joomla 4, Virtuemart 4 or reinstall virgin Joomla 4 and Virtuemart 4.

Joomla 4 is stable with Virtuemart 4?

On the site virtuemart.net/download does not yet have the Full Joomla 4 version with Virtuemart 4, I should manually install Joomla 4 and Virtuemart 4 with its components.

Can you advise me please.

Thanks in advance

Keep with joomla 3 latest. It is never need to uninstall vm and to install it again (reinstall). Just always install it over the old version. The vm updater works usually very stable.

So I would keep with j3 and install vm4.0.7 over it https://dev.virtuemart.net/attachments/1338/com_virtuemart.4.0.7.10730_package_or_extract.zip

Hello Milbo
Happy Christmas, I tried to subscribe again to OVH hosting and activate PHP 7.4 to try to update Virtuemart 3 under Joomla 3.10 to the Virtuemart 4.7 version thanks to your link that it works correctly.

I tried to change the PHP 8.0 version on my OVH hosting, the virtuemart 4.7 no longer works, I can't Add the new product or new categories.

  Virtuemart version 4.7 is compatible with PHP 8 ?

Thank you for your help.

Hello GJC Web Design

I tried to activate PHP 8.0 and install com_virtuemart.4.0.12.10777_package_or_extract.zip but the same problem, when I click on the add Product button there is a problem displaying (see the photo)
The same problem on the Add Category button

I also have the Joomla 3.11 categories problem, I can't access the categories anymore.

It displays error: Attempt to modify property "params" on null

Thank you for your help

[jenkinhill]

The error "Attempt to modify property "params" on null" is very often seen with a Joomla template that is not (yet) PHP8 compatible.  It can also occur with other extensions which are not yet PHP8-ready, such as older versions of weblinks or JCE editor.

There is also an issue with CSS not loading.

It's the HERA Template problem, when I tried to change the beez3 template. My category page displays.

Do you know a template compatible with PHP 8 of Joomla 3 & 4 with Virtuemart 4?

Thank you

[jenkinhill]

I use Hera on PHP 8.0.26 without issues, combined with the VP One Page Checkout, https://www.virtueplanet.com/extensions/vp-one-page-checkout

[tuaneric]

hello jenkinhill

Thank you for suggesting VP One Page Checkout, I will order. If I will fix the problem of my site with PHP 8.

Normally Hera template compatible with Joomla 3.11 and Virtuemart 4.0.12. On OVH hosting, if I leave PHP 7.4 it works fine. I only have the problem on PHP 8.

it shows the problem: Unsupported operand types: string * int

It confirms Hera template is not compatible with PHP 8 ?

Hello

1. I enabled the debugging methods in Configuration to see the error message.

In Product Menu, I click on the New button it displays error

Deprecated: Required parameter $name follows optional parameter $type in /home/Mydomain/www/components/com_jce/editor/libraries/classes/manager/base.php on line 82

Fatal error: Array and string offset access syntax with curly braces is no longer supported in /home/Mydomain/www/components/com_jce/editor/libraries/classes/browser.php on line 270


In Categories Menu, I click on New button it shows error

Deprecated: Required parameter $name follows optional parameter $type in /home/Mydomain/www/components/com_jce/editor/libraries/classes/manager/base.php on line 82

Fatal error: Array and string offset access syntax with curly braces is no longer supported in /home/Mydomain/www/components/com_jce/editor/libraries/classes/browser.php on line 270


2. Currently I use the isis template for Administration, I tried to change the vmadmin template which displays error: The template for this display is not available.

Can we install template vmadmin manually ?

Thank you for your help

Your errors seem to come from another 3rd party extension which is the JCE editor (com_jce).
Try to update it to the latest version.

Hi

I tried download JCE 2.9.32 and install.
https://www.joomlacontenteditor.net/downloads/editor/core

It works my virtuemart 4.0.12  , thank you !

I still have a Joomla 3.11 problem with my Hera Template, it shows error on my Index.php page

0
Unsupported operand types: string * int

Do you have the solution ?

[jenkinhill]

As I said above, earlier versions of the JCE editor are not PHP8-ready, I currently use JCE Pro 2.9.32 and have no problems. As far as I know, the Hera template checkout is OK in PHP8 so no need to get  VP One Page Checkout - I use that on all my sites as my preferred checkout system.

vmadmin_4.0.12.10777.zip is included in com_virtuemart.4.0.12.10777_package_or_extract.zip  = if you did not install the full package then you can extract the vmadmin zip and install that.  Then select it on Configuration/Shop settings/Advanced Settings
