Hi Rick,
Thanks so much for the new ideas and encouragement. I hope you or someone else will help me with my many neophyte responses to the questions you gave me.
1) Can you find the php.ini? The php.ini in the screenshot (see my previous post) is the only one that comes up when I "search" in the cPanels File Manager.
(There is one more copy, but it is in the Moodle folder which holds all the files in my Moodle 1.9.10 installation which I used until now)
2) Do you know how to log in as root? No, I don't know how or where to do this.
3) Do you know how to fine upload_max_filesize when editing php.ini? I made the changes to the php.ini files using the code editor in the File Manager (see that attached screenshot)
4) Do you know how to save your changes? I saved the changes to the php.ini files using the code editor in the File Manager (see that attached screenshot).
5) Do you know how to reboot your server? No, I don't know how or where to do this.
Thanks in advance to you or anyone who has the patience to continue helping me.
