If it is any help this is the fifth time i have had to re create the site due to the fact of this error.

Define "random". Does the same link sometimes work and sometimes not?

Cut/paste the error message(s) here.

Is it only in the admin area, or does it happen in the main site too?

What i mean by random is that it throws out the message for the same link(s) all the time. It is only on the frontpage though when someone tries to log out or access any of the features in the user menu. Basically it is just the standard 404 error but is is for a link that was working only a day before.
