I ask because a lot of my media sites don't work on my site after using SSL. Stuff like cnn, dailymotion, twitter doesn't work. All my addons are disabled. I am using the default xenforo forum theme with no edits. I have disabled listeners and enabled debug in config.php.
My site is on SSL. I have @JoshyPHPs9e Media BB Codes Pack installed. I'm wondering if that's interfering or not. So I've uninstalled it and all other BB Code Media Sites. I then used @Chris Deeming Reset BB Code Media Sites Query. I reset the cache first then used the main query on his resource. I still have all my addons disabled, listeners disabled in config.php, using default forum theme with no template edits and I have debug mode on.
I've cleared my cookies and temporary internet files in Google Chrome browser (I chose everything since the beginning of time) and I still can't view YouTube videos but I'm able to view it in Safari. I downloaded Firefox, first time in a long time and when I view a YouTube thread there I still can't see it not as a guest or logged in.
And it looks like all LiveLeak does is use SSL for logins. There are some people complaining about it - but like Mike said, the onus is on them (or serve your site without SSL or remove them as a media BBcode). SSL does have some downfalls - this being one of them.
