After install I'm having permission issues

after installing to shared server under a subdomain as administrator I don't have access to upload or change file in the data folder. I can however change them from the hosted cpanel. Please help. I've noticed that the permisson in the data directory can be changed till I get to my own directory. Is this an hosted issue or can I simply switch something in the setup files? Thanks


have you tried this nice script we have in our documentation?
