When you copied the stuff did you change its ownership? And is that chmod recursive?
try this (assuming you need sudo):
sudo chown -R hts:hts ~hts/.hts
sudo find ~hts/.hts -type d -exec chmod 755 {} \;
sudo find ~hts/.hts -type f -exec chmod 644 {} \;
// Note: change accordingly to correct user id
That should set the correct permissions.
