how do i get technical support?

Sorry if my query was vague, it's just the standard webpage I'm trying to update with new info.
Thanks for the steer , I've checked the directory permissions which are all writable OK.
There are some strange messages in the htExistance, such as 'Deny' which sounds not good, as below. Could this be my problem?

.htaccess Existance
