Getting 404 page not found

I recently ran into a problem with the newest version of the plugin crashing my site. I am in the process of seeing about getting my hosting company to update the version of php we are running.

In the mean time, i have had to re-install a previous version of the plugin.

The plugin displays the properties on the home page and the back end. When you click the link to view the details of the property, it gives me a 404 page cannot be found message.

https://dorseyproperties.com is the web site. any suggestions?
