When I update / save products in the backend I get a server error:
count(): Argument #1 ($value) must be of type Countable|array, bool given
The problem is related to the parent product to which the product is assigned without a price quoted
This error appears with PHP8 / VirtueMart 4.0.2 10661/ Joomla 3.10.9
Thank you, this error is fixed in the svn already
