If you get this error whilst working with WordPress:
“Deprecated: Function create_function() is deprecated in…”, the following advice works:
“It addresses the add_filter statement:
add_filter( 'option_page_capability_' . ot_options_id(), create_function( '$caps', "return '$caps';" ), 999 );switch it out, and use this instead:
add_filter( 'option_page_capability_' . ot_options_id(), function($caps) {return $caps;},999);We can see the usage of function(), very typical function creation instead of a deprecated create_function() to create functions. Hope it helps.”
I originally found a solution to this error log issue here:
