Hi,
After installing the 4.8 version of wordpress, I keep getting an error like Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘nt_big_border_wow_init’ not found or invalid function name in /home/mirandajoe/public_html/wp-includes/class-wp-hook.php on line 298 when I select the Slider Revolution Blank Template under the Page Attributes. Any ideas on what might be the reason ? Any kind of help would be greatly appreciated.
Thank you.
