could be a file permission issue.
Or operator error.
Set File & Directory Permissions
Unix & Mac Servers:
You must set the following permissions on the UBBâ„¢ files and directories. You can use your FTP software to set these permissions. For exact information on setting permissions in your FTP client, see the documentation included with that program.
includes/ directory: set permissions to 0777
files within the includes/ directory: set permissions to 0666
sessions/ directory: set permissions to 0777
templates/compile directory: set permissions to 0777
templates/ directory: set permissions to 0777
cache/ directory: set permissions to 0777
cache_builders/ directory: set permissions to 0777
cache_builders/custom/ directory: set permissions to 0777
files within the cache_builders/custom/ directory: set permissions to 0666
styles/ directory: set permissions to 0777
files within the styles/ directory: set permissions to 0666
tmp/ directory: set permissions to 0777
gallery/ directory: set permissions to 0777
directories within the gallery/default directory: set permissions to 0777
IN MY CASE THE ADMIN FOLDERS ARE SET TO 755 AND THE SCRIPT FILES ARE SET TO 644.
When you change the setting there are a few different ways to access it.
In your case group management is probably best.
Select the forum link to the right of admins.
ensure that you are editing the admin group at the top
Select edit post time
Enter time in MINUTES.
But to be honest I think for admins this is hard coded for forever. Depending on the version you are using.
Then select Update this groups permissions.
Try one forum if it is not working then go back to double checking file folder permissions.
