Hey, hey,
I saw a topic about this a couple of days ago, but that was about an outdated version of VM. Mine is up-to-date.
When I create a product, set categories and save all is good.
When I then add or delete a category and save & close all is good.
When I open to edit the product the added category is gone.
When I add or delete a category and save, the added category is gone or the deleted category is back.
Joomla! 3.9.16
VM 3.6.10 10211
PHP 7.3.17
MySQL 5.6.47
Annoyingly: This happens on the live site, but not on my localhost.
My localhost is not an exact copy, but the Joomla/VM versions are the same.
Can you help me solve this?
If you need any more information, let me know.
Thank you.
Wim
