The error "Deprecated: Function create_function() is deprecated" is looking at the latest version 7 . You should try with the old version of PHP.
I have another solution to remove this PHP deprecated error from class-woothemes-widget-our-team.php on line 324.
Follow the steps -
1. First of all, go to this path C:\xampp\htdocs\wordpress\wp-content\plugins\our-team-by-woothemes\classes\class-woothemes-widget-our-team.php , if you are on live server then follow the path public_html\wp-content\plugins\our-team-by-woothemes\classes\class-woothemes-widget-our-team.php
2. Edit class-woothemes-widget-our-team.php file with a text editor.
3. Go to line 324.
4. You will fount this code -
add_action( 'widgets_init', create_function( '', 'return register_widget("Woothemes_Widget_Our_Team");' ), 1 );
Change this line code to -
//add_action( 'widgets_init', create_function( '', 'return register_widget("Woothemes_Widget_Our_Team");' ), 1 );
Save the file and reload the page . The error "Deprecated: Function create_function() is deprecated in C:\xampp\htdocs\wordpress\wp-content\plugins\our-team-by-woothemes\classes\class-woothemes-widget-our-team.php on line 324 " will be removed
