I have no Admin experience but I'm the acting Admin for a friend's Moodle account / web site. So please forgive me for asking dumb questions.
Using YouTube videos, I successfully upgraded Moodle from 3.0 to 3.4.2. However, when I type my "Domain name.org" in the browser box, the older Moodle version appears with photos, documents, etc - stuff saved in the Database. The upgraded Moodle version appears at Domain name.org/moodle_stupidmdl/ but nothing from my Database appears in the upgraded version. (Sorry, I was super aggravated with Moodle last night when trying to upgrade.)
My host server is BlueHost and I know how to use CPanel to get to File Manager. I'm fairly sure the problem lies in File Manager. The Database needs to "point" to the upgraded Moodle version. (I contacted BlueHost first but they "don't know Moodle well enough" to help me.)
I named the Database "stupidmdl" (without quotes) using MySql Databases found in CPanel.
So I need help moving the Database from the old to new version of Moodle. And the new version needs to appear when you type Domain name.org into the browser box. I just don't understand the Moodle file structure (I think that's the correct term) in File Manager.
Thank you very much for any help you can provide.
