[Plugin: WP Help] Contributor access

Very good application. Love it!

Have a question on access by a/c of “Contributor” role.

Found that while help doc able to read by admin and Editor roles,
but not for Contributor role, it says “The requested help document could not be found” instead of show up the same doc!

Did changed to add_menu_page( …, ‘edit_posts’, … ) on admin_menu() function to allow showup the help screen. Please tell what else should change for contributor to read the help doc! Thanks

Please help.
Thanks
