 * Hi, I’m running wordpress version 5.6, with popup version 1.9.56 and it runs 
   great. When I try to update the popup version to 1.10.2, I get the header warnings
   below and the popups no longer work. The same issue persists even if I change
   to the 2020 theme.
 * Any help would be appreciated to resolve this so that I can use the latest version
   of the plugin. Thanks
