Joomla "error" downloading extensions.

I am having an issues installing extensions and modules. I know how to do it, and it has been fine in the past. However now for some reason I get an error that says this "Barbertrucking.com says: error" exactly. It has no description on the problem (I am using chrome) or any code. And when I use explorer it tells me that the page cannot be displayed correctly. I have tried all types of modules, the different ways of installing them, and different web browsers. I've also cleared the websites cache and made sure everything is up to date. Could you please help me? Thank you.
UPDATE: As I am working on this ticket I got a new error on chrome that says that the site cant be reached (this is when I click ok to the module/extension to start installing).
