I noticed, that in the new vmadmin template, when editing a product, its image disappears.
It turned out, that there was no image in the "Images" field in the "PRODUCT IMAGES" tab. After saving image naturally disappears.
Everything works fine in the old vmadmin template.
is this the latest vmadmin as the similar bug was fixed in product details related products dialog...
VirtueMart Administrator Template 4.0.12 (2021-01-28)
Why did you update this template? New doesn't always mean better.
Install version 4.0.7 - in this version nothing disappears.
I didn't set it up on purpose.
It was updated when installing Package VirtueMart 4.0.12 10777
Extract the template from the older version and install. Tel if it made a positive difference.
Install vmadmin 4.0.7 from virtuemart.4.0.7.10744
The bug remained
Well, you have the answer that it is not the fault of the template version (I have the same one) nor is it the fault of the last version of Virtuemart - I have the same version.
It's possible that some other Joomla plugin is causing this conflict. Also check what message your browser displays - maybe there you will find your problem there ;-)
Everything works with version vmadmin 4.0.14 10805
