I'm not sure if I'm asking this question on the right site, but as you can see in the attached screenshots there seem to be missing order numbers. The blue numbers are from Rupostel's One Page Checkout, the black numbers are Virtuemart (I guess). Has anybody experienced a problem such alike? It looks like an order is added to the One Page Checkout extension, but not to Virtuemart.
I checked the database and fount Order-2020-02-00030 in #__onepage_numbering. The timestamp of 00030 is 18:39:59, the timestamp of 00031 is 18:40:11. So just a few seconds later.
I can't explain what happened, why it happens and how it can be solved. Maybe somebody has suggestions?
