I found out the problem, but still haven’t reached a solution.
After the product was saved, there wasn’t a row in database for rule “Any” with the attribute “meta_key”.
Worked for me if I insert manually on table wp_postmeta:
Example “Any color”
meta_key: attribute_pa_color
meta_value: ” (empty)
Without that, “Any color” won’t work. Did you understand? I’m not the best one to explain XD.
I’m having this issue too!
I tested deactivating all my plugins but it didn’t work.
My “Any” variation isn’t being showed when there is a specific variation rule.
Look, I created two rules:
1- Specific variation, like color “Blue”
2- Any color (This doesn’t appear, i need to change to a specific color then back to “Any” option to make effect)
