PAYSTACK PLUGIN NOT COMPATIBLE WITH EVENT CALENDAR AND WORDPRESS

After installing the Event Calender and Event Tickets plugins, everything works fine. But once I install “Paystack for Event Calender” the entire site breaks. I have to go through the cpanel to delete the paystack plugin before I can get the site working again. As of writing this complaint both the Event Calender and the Events Tickets plugin have been updated 2 days ago, wordpress too. The Paystack was last updated 6 months ago and not tested with the recent wordpress. Is there something I can do? Do something fast about this please, I have an event coming up soon.
