Backend tabs not showing

[Nilsy]

Joomla! 3.8.12
VM 3.4.1
PHP 7.2.10
Apache
Linux

Having some trouble on the backend, creating/adding new products.
The pageview is without the tabs at the top guiding to the next section... (Product Information - Product Description - Product Status etc).

The "problem" this gives is that the selection area for Product Categories is empty, and the options for choosing a caonical category is the only option... which is wrong.

Any suggestions?

The fault I am getting is:

JQMIGRATE: Migrate is installed,
version 1.4.1

jquery.fancybox.min.js:13
Uncaught TypeError: Cannot read property 'hash' of undefined
at HTMLDocument.<anonymous> (jquery.fancybox.min.js:13)

I have tried to go to the file: YOURSITE\administrator\components\com_virtuemart\virtuemart.php and there add the statement

Code Select Expand

JHtml::_('script', 'jui/jquery-migrate.min.js', false, true, false, false);
as described in a previous post from 2015 (http://forum.virtuemart.net/index.php?topic=131821.msg455135#msg455135).
However this doesn't change anything here..?

Just updated to VM 3.4.2, and the problem is still there... any tips?

I've got the same problem :-(
...any track for solution ...

it's dramatic
...when I open a product in admin
it has no more category ...only "Force canonical category" ...what is it ?? but I'can select one category
then when I update
==> error 1062 Duplicate entry '199-0' for key 'virtuemart_product_id'

Thanks by advance for your Help

the reason you have no category selector is that is is fetched by JS/Ajax

as u have a JS error then the JS for the cats is failing

so u need to find and fix the JS error

have u tried deselecting fancybox in the vm config -> templates in the short term?

I've found the source of the problem:

A recent update of the extension "Simple Image Gallery Pro" to Version 3.5.0 causes the JS conflict. I've tried to play with the SIG Pro jQuery/PopUp -Settings without success. A downgrade to SIG Pro 3.1.0 helps to avoid the JS conflict.

Is it using a newer/different version of fancybox?

[Engholm]

The changelog says, something has changed to the backend GUI of SIG Pro:

Chosen.js and Swipebox have been removed from the backend UI (2 less JS dependencies to load). Fancybox v3.5.0 now acts as the main modal in Simple Image Gallery Pro's backend UI.

https://www.joomlaworks.net/blog/item/277-simple-image-gallery-pro-v3-5-0-released

I've created a topic in the Joomlaworks Support Forum. Hopefully, they will address this issue.

I think it will be the version mismatch

VM uses Fancybox Version: 1.3.4 (11/11/2010)  - Fancybox 3.5 is a totally different beast

[Engholm]

Yes, that's what Fotis from JoomlaWorks responses. The VM Fancybox is more the outdated:
https://www.joomlaworks.net/forum/simple-image-gallery-pro/49775-sig-pro-3-5-0-js-conflict-with-virtuemart-backend

I'm not sure how so solve it, since both extension seem to have a FancyBox - Backend dependency.

[GJC Web Design]

and I assume the naming conventions are the same so leading to conflict/confusion

Thank you Engholm!
I downgraded my SIG Pro and the categories are noe showing again.

I have been a paying VM Member for years... all the way back to J1.0 times actually.
This problem had me stumped, so I asked for help (as that what membership gives), and the response was "strange"...
Last answer was:

Message:
I have no clue. I am at on holidays actually. I am sure the reason is some non joomla plugin, which creates this problem. You could install a fresh vm somewhere, or just use our demo.virtuemart.net and compare the loaded scripts.

Made me laugh...

the answer is completely correct...

How can anyone except you know for certain what is installed on YOUR site?

"I am sure the reason is some non joomla plugin" - correct

"compare the loaded scripts" - correct

Conflicts are very difficult to find on any install without having complete access and control of that install..

[Milbo]

"I am sure the reason is some non joomla plugin" - correct

Actually, I did an error (holiday mode). I meant of course "non joomla/vm native plugin".

I do not know the function of the SIG Pro, is it used in the product edit to select images? So the question is, why it is loaded?

and yes it is time to update our fancybox. Why we did not updated yet? Because fancybox 2 was as far as I know not GPL anylonger.
