Did you actually manage to log in (cPanel and then Membership)?
You need to go to the site URL first, enter the login details to get past the cPanel security, and then click the 'Click to log on/out' button top/right to log into the private area of the site.
Then you'll be able to select the 'Directories' menu option, or use the other two URLs to see the pages.
The filtering is in the r/h sidebar as per the image I included with the original post. The same sidebar content/instance is on the Directories and Directory Entries pages I spent quite sometime yesterday reading through various bits of the documentation and watching some of the videos, which solved all the other problems I came accross.
The filtering works perfectly on the main Directories page, but once a single entry has been selected and viewed, the filtering has no effect - and I don't understand why/how it can be fixed.
Thanks for the details, I can see the filter form in the problem page: hidden link
I assume you are using the option "AJAX results update when visitors change any filter values" in view, this option only works when you insert the view's shortcode with option "Both the search box and results", in your case, I suggest you use the view's option "Full page refresh when visitors click on the search button", and test again
