I can't open one of my new .php pages
[Working on a Mac running OSX Sierra on DW CC17]
I'm baffled at why one web page on my site doesn't appear.
When I use localhost to browse the page, I get this unstyled page.

. . .
When I try to open the page online in two browsers, I get this error message, which has an unexpected URL entry.

What's unexpected in the URL that came up is the fact that the "W" in "pleasewait" is NOT capitalized, despite the fact that I typed my file with a capital "W" as shown here. . .

. . . and despite the fact that the localserver (XAMPP) shows the file with a capital "W", as shown here. . .

Nevertheless, when I try to open the page online from an accompanying page, the pathway clearly shows that a lowercased "w" is called for in "pleasewait2.php, as shown here. . .

I cannot figure out why a lowercase "w" appears in the URL, when viewing online and on localhost. All my files use an uppercase "W" in that file's title.
Am I missing something that might have caused this to happen? I cannot figure this out!
I've cleared the cache files several times. I even quit and reopened DW twice.
Here's the Home page. . .

. . . The problematic link is in the nav menu's bottom row; click the center of its three dark buttons titled "Acts 9:20 to Acts 17:34."
Thanks for your help.
