OAuth has become a gamble, and users are losing. An (incomplete!) list of errors I get:
- NULL (API breakage; filed bug reports for that in the past)
- Not logged in (just keep reloading https://tools.wmflabs.org/widar/ , after 2-3 tries it will tell you you haven't authorized OAuth, even if you just did)
- "The authorization headers in your request are not valid: Invalid signature" (this same error comes in two variants, for some reason)
- "Invalid token"
All this with the same code that ran fine a week or so ago.
PLEASE MAKE OAUTH WORK AGAIN RELIABLY!!!
(and please, for once, don't try "it's your fault" as default response...)
