Today I changed the stock quantities and after a couple of hours it changed itself to higher numbers. This happens almost every week. There's no error related log at the php error logs, this is one of the last entries that, apparently, has nothing to do with the stock but just the email or smth:

I've found this post but I don't think it's the same issue. In any case, I already tried the solution someone explained there, I'll see if that works.

Thanks for any help!
