Hey,
So I attempted to log in through that link and it originally told me my credentials were incorrect. I have lastpass, and for whatever reason there are 2 log ins for the website, the demo and the non demo. I changed my credentials to match the demo website and it takes me to a Joomla Open Source Content Management Home page which is essentially blank. Someone was working on this before I was, so I didn’t set all of this up and have no way to contact the person who last did this. The website, were it up, would be https://www.unclebillsfleamarket.com. Before it was under the URL https://www.demo.unclebillsfleamarket.com.
