Hey,
So at the permissions check screen I get the
Current Level = non-writeable
and
Desired level = writeable
I thought it was easier to understand and fix permissions when the permission check had the actual levels. An example would be 644, 777, 666, etc.
I just think it would be easier for people to fix permissions if you tell them exactly what to set on the actual install as opposed to going to the detailed install instructions in trac.
