My problem was due to where I copied the files which should have been the HTML folder which wasn't explained in the manual.
There is a difference between your home directory and your web directory/web-accessible directory.
The home directory is mostly for more advanced users who need a secure location for non-web-accessible files.
The web directory is less private than your home directory, because the files in the web directory are meant to be for others to access--well, generally the permissions are set to allow the 'world' to view, but not to modify your files). By access, I mean people can view files in your web directory via your web site or directly by individual file names if known.
So, essentially, everything you wish to published to the Web for others to see, it needs to be placed in the web directory. So, if your web host has set up your web directory to be "HTML" (make sure you don't rename it!), transfer your unzipped miniBB files to there.
yourHomeDirecotry (however your host has set it up to be called)
|----your private files sit here
|----HTML (this is your web dir!)
|----minibb sub-directory 1
|------minibb sub dir 2 ... etc.
How the default directories (i.e., your home dir and your web dir) is named varies from host to host. Some hosts label their web directories (common ones include public_html, html, web, docs ... etc)--only your web host can tell you. :)
Paul, based on RLS' experience and feedback, perhaps you would consider mentioning 'web (web-accessible) directory' in the official manual in the suggested manner below.
Currently the manual reads:
You should transfer all miniBB package files and folders to the place under your hosting, where you would like to see your forum running. Use File Transfer Protocol (FTP) client for that; hereby you should have FTP access (login and password) to the server. If you don't know what is FTP and how to use it, try to search the web first. Use a qualified FTP client program for this purpose, because files should be not broken or binary-converted when transferring on the server. Our FTP client recommendation is Total Commander.
Perhaps update it to read:
Using an FTP client software, transfer all unzipped miniBB files and folders to a sub-directory (e.g. forum) within your web directory. It is assumed you have the necessary access to do the transfer, it not, contact your web host.
The FTP client software we recommend is Total Commander.
Just a suggestion. :)
