Hi there ??
I don’t know if you guys thought of this by yourselves already or if you just gave up and tried another plugin but I’m coming here to talk about the solution since it made me very upset when I faced this problem.
On the general settings of FT Calendar there is a box that says “Enable SMART Post Ordering”, and it’s checked. Uncheck it and problem is solved.
Hope it helps a future user that would eventually come here after a brief time of grieving and sadness.
Cheers ??
