Thanks for the fast replies,

I tried the Reset pending Orders and Complete processing Orders options but the problem still remains. Is there something more I should do?
If not, the problem’s cause is probably the cache plugin I was using before and it was caching the carts of the customers. I need a generic one time solution so I can clean the carts of all my customers. Is it possible filter out from the database all the shopping cart related data?

Thanks in advance,
