So you can read here what my Theme Author has said in response to my requests for help on this: http://themeforest.net/item/humble-portfolio-and-business-theme/discussion/595690?page=33
Unfortunately, in his own words, he's "not very good with Child Theme[s]" so I am not expecting a lot more help from him there. He did release an update to the Parent Theme (v1.3) on Friday which I just applied. I was hoping there was some glitch in the MySQL database due to me having to manually change folder names in File Manager after the v1.28 update, but when I used FTP tonight to upload the 1.3 files, it didn't help. My Parent Theme version is now showing v1.3 which is good, but the Child Theme (which is the one activated) is still not "in control" of the stylesheet. Once it starts working, the Menus and H1, H2, etc. headings should all be Capitalized instead of UPPERCASE.
Chip, I appreciate your comments in directing me back to talk to the Theme Designer, but as I noted earlier, he's really not an expert in Child Themes. He lives in Spain and has pretty decent English, but I just don't know what else I can expect from him. Themeforest doesn't provide any "overall" tech support that I know of, so really I need to inquire for help on boards like this. You've shut me down on two different boards already, so I plead with you to allow me to continue to request help on here.
The site is live now and I assume my css and php files are accessible to someone who knows what to look for. Has anyone ever seen a case like this before? My child theme is called Humble-Child and is located in a folder named 'humble-child1'.
