 * I’m trying to delete all contributor-level users. I get the following error message:
 * > Warning: call_user_func(Bulk_Delete_Users::render_delete_users_box) [function.
   > call-user-func]: First argument is expected to be a valid callback in /home/
   > content/86/10127886/html/wp-admin/includes/template.php on line 924
 * Any suggestions?

 * Just a note to say I also get this same message upon accessing the “Bulk Delete
   Users” page, so not an isolated incident.
 * On an unrelated note I understand Sudar (the developer) has just had a new addition
   to his family – so congratulations!

 * This happens in some version of PHP, because I missed the `static` keyword in
   front of `render_delete_users_box` function. [https://github.com/sudar/bulk-delete/issues/31](https://github.com/sudar/bulk-delete/issues/31)

 * Thanks 🙂
 * Just give me time till next week and I will release a fix for it. Till then you
   can just add the `static` keyword in front of the `render_delete_users_box` function
   and this erorr should go away.
 * Also let me know the version of PHP you are using. I should add it to my test
   case as well so that this doesn’t happen in future.

 * I have fixed this in v4.2.1 of the plugin.
 * Kindly update the plugin and let me know if you still face this issue.
