Hi,
I created the apps at facebook.com and twitter.com.
I activated Facebook and Twitter login in the Social Networks of my site administration and entered the the Application keys and secrets.
In my php.ini: allow_url_fopen = On
Now when I try to login using facebook, it takes me to the FB website where I enter my FB credentials, then it redirects me to http://www.mysite.com/members/check_fac ... ah-blah.... the page loads completely but it is entirely blank.
Same thing with Twitter.
Does anyone know what could be wrong? Thank you!
