Hello! I'm having the following problem:  If I choose a time slot for reservation and fill out the form in the frontend it says "Thanks for your reservation!" (so it should have worked successsfully). However there are no reservations shown in the backend dashboard of the plugin. Last year this process worked just fine. I found this issue in the wordpress support too. One user is also experiencing the same problem: https://wordpress.org/support/topic/issue-cant-save-a-booking/ Could you please give me some advice on how to solve this issue?
