Hello kayskeem,

Thank you for your question about the Joomla authorization error. Without being able to duplicate it, we can only take a guess, but here are some suggestions.

Is the user you are using allowed access to this area?
Is this an article that was made public in the back end?
Have you cleared your browser cache?
Have you adjusted the Search Engine Friendly URLs in the back end?
What specifically did you do from the last time it worked until the first time you got the error?

Kindest Regards,
Scott M
