When I visit [[mw:Special:OAuth]] or [[mw:Special:OAuth/manage]], I get the following:
Error: <oauth-client-invalidrequest>
The page source is:
Error: <oauth-client-invalidrequest>
This error shouldn't look so terrifying. It should be wrapped in the user interface and handled gracefully. Compare with [[mw:Special:MWOAuth/authorize]].
Version: unspecified
Severity: enhancement
