When using the Internationalisation module on a site, a white unstyled exception page is shown if page slug does not exist. When deactivating the module a styled 404 error page is shown.
The white error page is only shown if page slug does not exist (e.g. /page/foo). If the controller part of the URL is misspelled (e.g. /foo/welcome) the correctly styled 404 error page appears.
The thrown error is:
Omeka S encountered an error
Omeka\Api\Exception\NotFoundException
