Users can no longer post replies to other people Threads
 

Hello*

Recently no user including Administrators is able to post a reply to an existing thread.
(Everyone gets the usual permission denied page when trying)
This might be caused by a recent db Crash* but everything worked
just fine after the crash.

I checked the permissions for all Usergroups in the Admin panel.
"May post replies to other threads" is suddenly unchecked!
When i try to re add the permission and save* it says "saved successfully".
But the setting is not saved. When i reenter the usergroup setting dialog* it is
again unchecked.

Modifying the forum permissions for a usergroup overriding the default permissions of this group
also doesn't work. Adding a new usergroup and changing the permission also doesn't work.

Modifying other settings for forums or usergroups works fine.
Checked db* including myisamcheck - no obvious errors.

So I'm stuck now... I would modify the permission settings directly in the DB Table*
but i don't know* how the permission system works in detail.
---------------------------------------------------------
Update: I digged a bit deeper into the permissionstuff* created a new usergroup for testing*
removed all the forumpermissions* checked usergroup tables "forumpermissions" column*
"0" -> fine.
If I add forumpermissions now in Adminpanel* i can see the corresponding numbers in the column*
as they are defined in "bitfield_vbulletin.xml" eg* if i set "can create posts"* 16 is written into the column*
-> also fine.
everything works fine withn one exception. If i check "canreplyothers"* 0 is written into the column* which causes my problem...
Also if i write the "64" manually into the database field and check the permissions in Adminpanel* the canreplyothers radiobutton is still unchecked.
Really strange:(
