Thank you for replying, Steve, much appreciated!
You must have a magic touch because both addresses open up now in the browsers Chrome, Firefox, Safari, Internet Explorer,
EXCEPT for http://www.stellalevak.com/sherlocka/ which doesn’t open up in Chrome and instead I still get a blank page with:

Index of /sherlocka

Parent Directory
cgi-bin/

I need this address http://www.stellalevak.com/sherlocka/ (with no caps) to open up correctly everywhere.
How come it doesn’t open up just in one browser (or is this happening just to me?)?
BTW, I use Chrome when working on my site in WP. I did try logging out of WP, clearing all caches (WP and Chrome) and then opening the page in question but still no go in Chrome.

Thanks a lot, Yorman. Very extensive and clear answer. Will try to do one of the things you suggest.
