still not workin'
is there some were on the actual forum you have to upload them too?
yes, you have to use ftp to upload them to the server, since you are on the free one, you cant do this. the free phpbb boards don't allow you to upload anything to the server.
if you want to be able to make any changes to your board, you will have to get a hosting account that gives you access to the files via ftp.
also, the free ones do not give you the ability to make database backups
