Got it!

1) In the plugin folder find the file OSCFacebook.php
2) On line 121 replace
"header( 'Location: ' . osc_base_url() );"
with
"header( 'Location: ' . osc_user_profile_url() );"
2) On line 91 you see this code
return self::$facebook; Move this line down using enter key and place this code
header( 'Location: ' . osc_user_profile_url() ); on line 91
Saven & Close this file
Now, open the index.php file in the plugin folder.
The plugin is setup in such a way that the init function is loaded with every page load, this is not needed and since we want a working relocation we will add an if statement.
Replace the function called 'fbc_init()' with this function:
function fbc_init() {
//Let's check if we're on login page, if not no need for init
if(osc_is_login_form()) {
$facebook = OSCFacebook::newInstance()->init();
}
}
It works for me, let me know if you run into issues.
