I'm reaching out to all my "more technically gifted" programming people with a desperate cry for help.

I'm trying to update a WordPress site for a client. I deleted the original home page because it wouldn't accept any edits, so now I've got the 7 pages he requested. They're done & visible when you visit his site. The problem is that the original home page still exits online - yet it's not available to me when I'm in the editor for WP. 

I've looked in different WP fora and all tell me to go to the "Appearance" tab or "Settings - Reading" but I'm discovering that my dashboard doesn't give me the any of the following options: Home/ Store/ Feedback/ Appearance/ Users. I'm running 4.0 and he updated to 4.0 also. My settings gives me virtually no options - and certainly not "reading."

I don't know how/ where to type in phpMyAdmin to try to change the site url or home values (and I'm not sure how to do that, anyway, but I read somewhere that it would help). I've cleared my cache, so it's not that the old page is lingering on my computer somewhere. I can't figure out how to get to the root install directory- or even if it's necessary.

Suggestions much appreciated!
