Thanks for you responce.
1. The Upgrade option is the normal price for a new plugin for 3 websites. Don’t I get any discount? My Personal Lincence key is still more then 3 month valid (Expires on: Feb 21st, 2018), but I have to order a complete new one for 3 websites at the normal annual price of $ 149.
2. I installed the Divi compatibility extension alongside the Events Calendar plugin (not PRO) but still have issues with Divi. I cannot use the [Divi Visual Builder] because of Plugin conflict with your Events Calendar plugin.
Hope you can help.
Thanks in advance!
