i have an issue with one of my variable subscriptions.

the product hast 3 different sizes, each size has 4 subscription intervals.

one size (and all the intervals) keeps getting out of stock, even with the stock management disabled.

i’ve googled a lot and tried all suggestions like:

• clean transitions
• regenerate product look ups
• set the stock to 1000 in the meta table
• deleted sessions

every solutions lasts only a couple of hours (at least), but then it switched back to -300.
I cannot delete the product, because then every running subscription would be canceled.

Do you have any ideas?

thanks!!
