General Settings

I don’t know if there is a video or document that may have already answered this, but what are the general settings on the back end? I have a couple of websites that I am trying to use this directory for and haven’t had any luck on any of them.
I thought that I could simply download the plugins and Child Theme, and adjust the setting to reflect I home I want to charge and be on my way. That hasn’t been the case and I am getting different errors and they are consistently the same across the board on all my sites. I am not looking for anything that is sophisticated, I just want to plugin and go.
On some of the example themes I have seen that people have been able to change to the Menu to reflect different title with regards to the Geothemes..I can’t seem to change anything. For example If I want to change “add places” to “add mechanic or something like that”
On top of that, once I publish my website and the links and click on the “add places” link I get the Error 404-page not found.
When I log in on the back end..I can still see everything
If I am able to click on “add place” and lucky enough to get to the page of adding my email and name..I then get “not able to add new user” message.
On the Geodirectory website..the demo..I see how they have attractions, events, hotels, restaurants..and then for “add listing” the drop down shows add attractions, add events, add hotels, add restaurants…how do you do that? I want to be able to do that?
Having said all that..I absolutely love the concepts and the potential of what this can be. Great work! I am sure I just can’t figure it out!
