[Plugin: BC oAuth] BC auth blank page

I have the same issue. When WP debug is enabled, these are the errors I get…

Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of call_user_func(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file in /path-to-site/httpdocs/wp-content/plugins/bc-oauth/lib/php-openid/Auth/OpenID/Consumer.php on line 1184

Finally got a chance to poke around and the white screen fix is VERY easy.

In bc-oauth-loader.php (btw, proper naming convention for this file should be bc-oauth.php), you simply need to add the following hook:

add_action('init', 'bc_oauth_init');

The problem is that the login action is trying to use wp-load.php, but there is no hooked function there to catch the login request. The init function, bc_oauth_init(), is hooked to wp_ajax, which only used by requests sent to /wp-admin/wp-ajax.php – since I don’t know if that’s actually used or not, I simply added an extra hook that allows bc_oauth_init() to catch requests from wp-load.php.

Everything works great, now.

😉

Did you add:

add_action('init', 'bc_oauth_init');

directly above:

add_action('wp_ajax_bc_oauth', 'bc_oauth_init');
