How can i edit my adress or logo?
If you try changing the adress in the footer or logo you just need to right-click the text or logo and select "edit".
If this isn't possible it could mean that the adress or logotype isn't included in the template.
To add this information to your templates is easily done, because many pages and subpages are using the same template. You just need to change the information in your templates to change it on every page using that template.
This chapter in the online documentation describes how to change modules in your templates.
