Joomla Free extensions

Hello master!

Since the last day i get an error on my joomcore facebook pro plugin page
https://salsabachataevents.at/test

array_reverse(): Argument #1 ($array) must be of type array, null given

i tried now to add a new module (enterig token, id) but the same problem (but facebook login in the module worked)

can you check whats the problem with your plugin?!?
i dindt changed anything

thanks!
René

i had to deactivate the link to my events and created a hidden menue and subpage where you can test!
