I have activated the login/subscription via Facebook option on my board, but the problem is, the FB button shows only when I'm on Google Chrome from my PC.

The button doesn't show either when I'm using Firefox and Safari on my iPhone 6 and iPhone XR.
I've tried disabling those plugins that could interfere with the FB API, but nothing has changed.

What could be the cause of this?
Thank you very much!

Hi @zell

Please try this small CSS code. Put it in Dashboard > Forums > Settings > Styles > Custom CSS Code Textarea. Save it delete all caches, do Ctrl+F5 on forum front-end. Then test it on other mobile devices. Because mobile browsers have a hard cache, you'll not be able see the change immediately.

.fb_iframe_widget iframe {
     position: relative!important;

Also please don't use Private Session of mobile browsers. Facebook doesn't allow use Login Button on private sessions, it doesn't allow use Cookies so make sure you use regular (default) mode of mobile browser.

Great, now the button is appearing in Safari on my iPhone (it is not centered, but it's not a big deal).

Thank you! 😀
