Virtuemart 4 - Unable to add new producet

[steveml]

Joomla 4.3.2
Virtuemart 4.0.12
PHP 8.1.20

I currently have an issue - when attempting to add a new product I'm unable to do so because of a spinning icon in the Product Category field (please see attachment). The icon continually spins and never resolves?? I don't have any unusual third-party plugins installed. The website was recently rebuilt and uploaded to a new hosting provider, and it is only under live testing that this problem has recently been identified. Any help would be greatly appreciated.

Any PHP error displayed break the ajax loading.
Disable PHP error display and Joomla/virtuemart debug and see if it work

i have the same problem.

Joomla: 3.10.11
Virtumart: 4.0.12 10777
PHP: 8.2.8

When I change a product it does show the label of the category selection list. However, the selection list is not shown. The canonical category list is shown nicely.

same reply as S 42 .. errors will break the ajax .. I really doubt even the latest VM4 will work without some bugs on php8.2

Why push it .. be patient and just use 8.0 or 8.1

and Virtumart: 4.0.12 10777 is so old and was never fully stable .. the current latest is VirtueMart 4.0.23 10895

[ViPeS]

the current latest is VirtueMart 4.0.23 10895

Can you tell when this update for "VirtueMart Supporter Membership Bronze" will be distributed?
I'm still prompted for 4.0.22.10864

PHP 8.0 and also PHP 8.1 bring no improvement. The version 4.0.12 10777 is half a year old. So not so very old yet!

So not so very old yet!

has nothing to do with old! It is whether bugs have been fixed!!!

And u haven't followed any of the advice .. check the console and response from ajax calls and see if the json returns are corrupted by error messages etc...
If so find and fix/report the messages/errors

I just set up a test site using VirtueMart4.0.12_Joomla_3.10.11-Stable-Full_Package with sample data.

Joomla: 3.10.11
Virtumart: 4.0.12 10777
PHP: 8.2.5

I see no issues with the category selection list when creating or editing products. This is despite J3.10 and VM4.0.12 having reported problems with PHP8.2

[AlfredJK]

@jenkinhill Thank you for this test. Do you have any idea in which corner I should look for the solution?

[jenkinhill]

@AlfredJK I have no idea, except try what GJC recommended

[AlfredJK]

BTW: In the Product Category Form, the selection list for the parent category is  also missing.

@GJC: Sorry - Without and with PHP debug and joomla debug it doesn't work either. With PHP debug I only see these comments (see attachment)
I have also been debugging via browser (inspection screen) for some time. However, I can develop software, but am not a php / web programmer. My knowledge in this area is unfortunately limited.

Cache does not play well with most cart, VM no exception.
urn off any cache component or plugins.

I assume u have switched off the add to carts in the cat view now?

but what is the ajax call and response in the console when it is enabled?

[AlfredJK]

Maybe a silly question, but where can I turn this on? Have looked all over the backend. Also in the forum, but there I find you have to rule it in the template override?

[AlfredJK]

and further searching - the selection list is compiled but after rendering the page, the display style none is added.
Does anyone know where and why the style display option none is applied?
