 * Hello,
    I bought the pro version of the plugin, and i have a message popping 
   every time i make a change on my calendar. It says “There was an error with the
   request” Also, when I click on Save Changes, I get an error 400 page, and nothing
   is saved. Before installing the pro versino, i have deleted the free version 
   as it was told. How to solve this please ? Thanks in advance !
