Thank you very much for taking your time to reply on this.
Two problems arise, however:
The plugin Adminer is no longer available, and I can’t seem to find an alternative.
I’ve tried to peek into the Database (MySQL admin), to locate the numbers, but unfortunately I’m not smart enough to locate them.
Now I have updated a lot of plugins, themes, etc., because my customer never took the time to do that. After that I’ve been placing test orders again, and the gab is more than 80 ID numbers.
That says you’re right about how the gabs occure.
But: Customers refer to order numbers that are in the gabs, when they call to ask “wtf is happening to my order”…?!?!
