OK, I'll try and be a little bit more specific...thanks for replying.
In attemtpting to set up my e107 site. Each time I try and make any modifications, such as Add user, Change Site Link Button, Set Up User Registration/Login, Edit Sign Up Page/Login, adjust any Site Preferences, Create Pages, etc. I am diverted to a white blank page with only this on it ..Unauthorized access!
I had been using an old outdated e107 version before this. I did back up all my databases before installing the new version. I am at a loss as to why I can't go beyond logging just myself in and nothing more.
