Thank you Ken and Howard for your detailed efforts and encouragement to get this (me ) sorted out. I will follow all the above advice again and report back - my effort. In December I have done a successful install of http://www.modtrainingcollege.co.za on another server, which we start working on next week. So yes I also think it is not a Moodle problem as such, but a server problem, albeit very obscured.
I have also requested my service provider (Afrihost in South Africa, and yes I know what you mean about ISPs) to install Moodle on the server. 24 hours later and no response. Will have to wait for Monday to get feedback.
For the trecord, I do have a so-called "Managed" dedicated server package which they maintain, and therefor I have no root access. Which seems to become an increasingly bigger frustration. I will probably use the wrong terminology here, but the server is supposed to be dedicated (oge1.co.za) and hosts several domains (batlearning.com, jaguar.org, etc), amongst others this 360growth.co.za domain. So yes, many "customers" share the IP, although they all belong to me. I have WHM control panel access, but not root to that (the server). So if I understand this, I have root to the domain access, but not the server and OS.
eportfolio should not be on this domain and/or server in that format (as a folder), although I am trying out Mahara on the same domain. My confusion is how Moodle install will know about it or consider it as a source or target for a file/data?
I do have cPanel and phpmyadmin access. Yes the DB user have full rights. Regarding the change from mdl_ to xxx_, just something someone on a forum years ago recommended one do if you might combine info from different DBs and Moodle installations. Yes, each installation/instance has its own DB. Is it a potentially bad practice?
The DB socket issue I will have to investigate and learn more about as I do not understand the question regarding it yet. I have never set/changed it though.
The UTF8 should not be an issue, but I will specifically check that with the next install/create. The server has been set up with UTF8 as default.
Thanks for the reference to the installation intro. I will refer them to this post as well.
I am doing the index.html right now.
Thank you again
