Problem identified / solved (sort of)... (styles, other features not working...)
The issue seems to be Mac related. When I saved the config.php file in BBEdit, I used Unicode-8, no BOM, which is my default setting. I also tried Dreamweaver's internal editor. Neither showed any problems with the file, nor did any other editor on the Mac.
Once I checked the file in vi, I saw an inverse-video "?" as the first character, indicating something wasn't right. So, whatever the Mac editors are doing, it isn't a good thing when uploading to a remote server. The Linux box clearly doesn't use the same encoding.
I'm up and running after six hours of staring at the files. I should have started with vi, I guess, but I'm pretty much a Dreamweaver junkie for everything I do on the Web.
