Well I have to update the documentation asap....thanks for the hints to improve this document.
It's enough to download the core system to test installation. If the installation is ok, without errors, it's very easy to upload and install the other modules.
So please check with the core system and you will save time for the upload.
If you unpack the OPN zip files, you get a directory tree:
openphpnuke/html/ a lot of directories.
You don't want to use a subdirectory (No subdirectory is necessary ), so in your case upload all files and directories which are located in /html to your directory /public_html.
You should get something like this at your webserver:
/public_html
index.html
master.php
install.php
....some more files
/admin
/api
/....a lot more of directories and subdirectories
Use a good FTP program. Read in the doku about
