I just updated to VirtueMart 3.8.6 10373
I added a second category to a product (in an attempt to make child-category products visible on the homepage), then I took the category away and now when I go to
https://www.irmas-hemerocallis.nl/administrator/index.php?option=com_virtuemart&view=product
I just get
Quote1054 Unknown column 'Array' in 'where clause'
frontend still seems to work. But I can't edit any products now. So glad I just made a backup before updating.
