I am not sure what you are talking about here but I can tell that one host I deal with Inmotion hosting .
On new accounts they have a new server cache system that interferes with making changes in the control panel.
Where you need to submit several times to make a change stick in UBB.
In the cpanel is a option for controlling this cache and I opted to exclude ubbthreads.php from the cache and the problem was resolved.
It interfered with things like permission changes and most all other settings changes.
I have another older account with inmotion that does not have this cache system that still works fine.
