I updated my WP version to 3.7.1 and now i am getting the following error right on top of the page -
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'responsive_theme_data' was given in /home/content/g/s/i/gsiagoa/html/online-tutor/wp-includes/plugin.php on line 429
I have tried disabling all plugins but the error persists.
How do i fix it?
