Wordpress Version 2.9.1

Version 1.1.4.dev (also tried the version that you can now download off wordpress plugins)

I'm attempting to restrict editing capabilities to a certain user for a certain page.  I followed the guide and went to Pages, chose the page to edit and then underneath the Editors section, I clicked on Users and then selected the user I want to be able to edit the page and applied the changes.  When I logged in as this user, I got a message saying I don't have permission.

I logged back in as admin and went to Roles, then Pages.  I selected assign for selected and subpages, then selected the user, then I scrolled down and found the page I wanted to modify and checked the box beside Page Editor and the username was beside this.  I then clicked update.  I hope I am doing this correctly…please advise.

This is the error I received:

WordPress database error Incorrect integer value: '' for column 'date_limited' at row 1 for query UPDATE wp_user2role2object_rs SET date_limited = '', start_date_gmt = '0', end_date_gmt = '2035-01-01 00:00:00' WHERE assignment_id IN ('6') made by do_action, call_user_func_array, __lambda_func, scoper_admin_object_roles, ScoperAdminBulk->role_submission, ScoperRoleAssigner->assign_roles, scoper_query, scoper_db_method, call_user_funcWordPress database error Incorrect integer value: '' for column 'content_date_limited' at row 1 for query UPDATE wp_user2role2object_rs SET content_date_limited = '', content_min_date_gmt = '0', content_max_date_gmt = '2035-01-01 00:00:00' WHERE assignment_id IN ('6') made by do_action, call_user_func_array, __lambda_func, scoper_admin_object_roles, ScoperAdminBulk->role_submission, ScoperRoleAssigner->assign_roles, scoper_query, scoper_db_method, call_user_func

Thank you for you quick reply.  I will try this fix in the morning and report back.

What restrictions and roles did you apply?
