I just checked the permissions and they were OK. This seems to be a different problem than the Mod's access to the CL forum. Heavnbound's account shows the same signs of corruption that are shown in three moderator's accounts that can't see the mod forum. I will check some files:

Other corrupt files:

f=2504by497
mustange70
fordborn

-All three of you so far.

The consistent sign of corruption I have seen is that the following item has no Y/N setting in the file:
"Pop up a Notification Box When a Private Message is Received"

Just for grins... Can you guys check your User CP and see if a setting for that option shows? Then see if you can set it. After you have set it, test your access to the CL forum. When I have set the option in the past from the Admin panel it has made no difference. Let me know what you find out.
