Setting canonical locks me out

Developing with Concrete

Under System and Settings I have set the canonical url.

But when I go to login, I add my name and pw but then get a Page not found error. Help!

Can I solve this through the backend?

Yes you can solve it by editing the application/config/generated_overrides/site.php file and look for the ‘seo’ section, make your changes and save the file.
Try changing the seo section to this:

'seo' => [
                'canonical_url' => '',
                'canonical_url_alternative' => '',
                'canonical_tag' => [
                    'enabled' => true,
                ],
            ],
