@sagraphics. Thanks for replying. Well, if you say you haven’t edited it, I will take you at your word. However, I had to ask just to make sure, since the behavior I see is not replicated on my servers.
Did you look at my screenshots? I decided to replicate the same situation on one of my public test servers. I apologize if the use of your files constitute any violation of copyright. However, I will remove them as soon as you request or as soon as we resolve this issue, whichever comes first. Please have a look and let’s see if the behavior is the same as on your server or is different: http://familytree.michaelgilkes.com/certificates-test.html
On this server, I have installed Easy Folder Listing Pro 2.8.5. From testing, it works as expected, which is different from what I see happening in your installation. This is why I say that it puzzles me that your setup is acting differently, since it is the same code. I will run a few more tests to see if I can figure out what is going on. However, please check the site and verify that the test site works as you expect.
Thanks.
