All my flashcards have been postponed too far long

Hi all, recently I started to use a new computer so I installed my Ankiweb on it, but after I synchronize with my account I realized that all my flashcards were postponed almost one month from today. Therefore I’m not allowed to study them until that time. Help, please.

That sounds like the same issue as mentioned here:

If you replace the ‘8’ with the number of days you want to shift cards, you should be able to correct the problem in the same way.
