Dashboard suddenly giving Page Not Found
PermalinkShe could possibly delete system pages.
you'd know exactly what version you are on
have full ftp access
have an installation where the core has not been modified at all.
If I were you I'd take a backup of the database and the codebase.
I'd then replace the core with a vanilla instance
by which I mean I'd download the same version from concrete5.org
upload this to wherever your core resides - which is normally /website-root/concrete
but might be under the updates directory if you have an upgraded instance.
But, you must make sure you replace the core files and not those in the root.
If you are uncertain ask any questions before you do this and like I said do a backup furst.
