Well some editor reported me this, then I’ve checked the error log and I’ve found this:

[13-Oct-2013 21:22:03] WordPress database error Table ‘diytech1_wor5.zhb_bp_groups_groupmeta’ doesn’t exist for query SELECT group_id FROM zhb_bp_groups_groupmeta WHERE meta_key = ‘forum_id’ AND meta_value = ‘2874’; made by require_once(‘wp-admin/admin.php’), do_action(‘load-tools_page_bbp-repair’), call_user_func_array, bbp_admin_repair_handler, call_user_func, bbp_admin_repair_group_forum_relationship

Since the last update on bbpress editors cant login on wp-admin, they see a blank page.

How to fix it?

I cannot reproduce this WordPress editors can see the dashboard fine with these roles assigned:

• WordPress Role: Editor
• bbPress Role: Participant

Also the error text you have above has nothing to do with this, you only get this error if you run the repair tool ‘Repair BuddyPress Group Forum relationships’ and you do not have BuddyPress installed.
