Facebook Login button not showing
I enabled the facebook login, but it does not show up on register/login screen. I tried 3 different browsers and it does not show up.
Why is it not showing?
Only clearing the cache brings the button back.
What cache you mean? Where you clear the cache?
As you've already mentioned this is a browser cache issue. There is no way to fix this from wpForo side. In most cases people don't get such problem. I think this is your browser configuration specific issue. Try other browsers and devices. I'm sorry but we can't fix browser cache issues. This is out of plugin environment.
