If I place more then one calendar on the page, all of them will be changed if I go to the next/prev month. That's not a problem, but if I give them different categories, browsing through one of them will reset all calendars, and all of them will show same results. How to fix that?
P.S.
I am waiting for Licence Key from the client, hope I will get it in the morning, so will check your forum.
