If anyone got the same issue, I solved it by going to the WordPress General Settings page, then I saw that my blog URL was set like this : https://mywebsite.com/blog
so I added www to make it https://www.mywebsite.com/blog
. This immediately solved the looping issue I experienced with this plugin.
As I already have a template installed on the blog, the widgets of this plugin do not display very nicely, but I’d like to thank the developer for sharing this with us (merci au développeur ??
I’ll try to tweak the plugin to make it work with my graphical template.
