Ya the arcade settings are set correctly, and the https is also correct. This has more to do with windows edge and allowing flash to function I think. I dont use Edge, so I cannot help my friends fix it. Even from the advise from the edge help site. I use chrome and every visit to the arcade i have to allow flash from the site settings and it works for me. today. but for some reason it does not always work.
My solution for https was a code of script in my .htaccess file. Would it be helpful to post it here?
i like giving back what i can, so here it is maybe someone can benefit or maybe it needs work or maybe there is a better solution. Dont know, but check it out.
in .htaccess
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
This forces https throughout the site. I do not know which css files have the actual links. but when i find a link its always just the portion the comes after my domain starting like /home.
