From the icons it appears you are using a very old version of RoboHelp Server (version 8?) Please let us know what version of Robohelp Server and what version of RoboHelp (the client authoring application) you are using.
First of all, I'm not clear as to what you mean by "not able to see the content.". Do you mean you can't see the project listed in the Projects panel (your screenshot). Or, you mean you can't see content of your site in a Web Browser if you chose to "View Project"?
First, be sure you are using the Single Source Layout called "WebHelp Pro" and not WebHelp. I have not seen "null" before.
I see the Area you have published to is called "general". This is the default Area for projects.
If you have created an "Area" called Journal, you must drop the arrow down to select Journal (or whatever Area name you choose.)
Then, when you go to Projects, you select Journal or whatever Area and your project should show up. If it does not show up, you may have to click on a "Reload" button to refresh the list. (I can't see it on your screenshot. It is usually down below on that screen.)
Post again and explain a little better what your issue is.
