Unable to save/edit products with combination after updating to 8.0.2

[m0ttan]

Hello.
I have an error that happens when i try to add or edit a product with combinations after updating from 1.7.8 to 8.0.2 via 1clickupgrade module. I get an red error message and loading sign that keeps loading forever (only after i hit save or click back to catalog) - see below

in dev mode and console i get following error:

 

Mentions of solutions that i already found and not applicable in my case:

not related to iframe or other html code, description is 100 characters only text

not related to stock management - i have not enabled the stock management

i can create and modify product without combinations

in debug mode i have no error displayed

cleared cache, etc

Any ideea?

Advanced Parameters > New and experimental features > switch it on..  Now you will have no issues

what you can do..  once you have finished editing the product.  switch experimental feature off.

In my case it was just the opposite. I have to disable the Experimental feature - New product page to edit the product.
