Welcome and thank you. Did you get my email with questions about e107 version and your github account?
I can't help you with social login, it is core stuff.
About CDN. I suppose you use 1.4.x version for e107 2.3.0
bootstrap and font awesome libraries are loaded from the core, there should be settings to load them locally in core preferencies.
Theme itself uses only fonts external:
in theme.php this:
it is pretty easy to change to local source, so just confirm me you mean this... in fact, I could add this to theme settings, but nobody has asked for this yet. But change is easy, so just let me know. You need to download those fonts locally, correct?
The link to video is in theme preferences, so just insert your path there.
If this is not set, in theme_shortcodes.php is set default path:
$videourl = "https://storage.googleapis.com/coverr-main/mp4/Traffic-blurred2.mp4";
But again, there is the new version for e107 2.3.1 prepared...
I sent you a private message with my email. I will install 2.3.0 with PHP 7.4 (or what is your PHP version) to see what can be done in this version.
Answer to first part of your question:
- Go to Preferences
- Select Libraries
- set Use CDN off
Video URL is absolute, with https...
Do you know how to use google fonts locally?
Are you part of this:
If not, login is good idea.
Done. You should get an invitation to the repo with local font loading.
You can check this (and core settings) with CTRL-U - displays source code and there is no CDN, or external sources now.
