Hello! I'm seeing the following warning in my error log regarding TubePress:
[28-Oct-2013 16:16:38 UTC] PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'tubepress_addons_wordpress_impl_Bootstrap' not found in /home/southern/public_html/wp-includes/plugin.php on line 429
Can someone tell me what this is and how I can resolve? Thanks!
