Hey Gary, it appears your Zuka Themes site is having some issues, I am trying to access it to see what you been up too but there are security messages when accessing the site from https://themes.tiki.org/Themes and when I click on "Demo" of one of the themes I get the security message below.
Did Not Connect: Potential Security Issue
Firefox detected an issue and did not continue to demo.zukathemes.com. The website is either misconfigured or your computer clock is set to the wrong time.
It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.
What can you do about it?
demo.zukathemes.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
Your computer clock is set to 5/14/2019. Make sure your computer is set to the correct date, time, and time zone in your system settings, and then refresh demo.zukathemes.com.
If your clock is already set to the right time, the website is likely misconfigured, and there is nothing you can do to resolve the issue. You can notify the website’s administrator about the problem.
Also Gary, when access your site from the web, and try clicking on "New Themes" for example, I get taken to the top of the page, same with the other link headings in the same row.
Just a heads up Gary.
