Hi,
Getting this issue on a more or less regular basis: every month or so. At some point, saving a URL directly from the browser using a browser extension stops working. All the extension (which is made by a third-party) returns is “Post XXX not saved. Error” Only way to save a URL to Pinboard when this happens is to do it manually on Pinboard website: copy-pasting the URL, page title, comment if any, and tags. Not sure if it’s an issue with API, the servers, both (not a programmer myself). Usually resolves itself after 24 to 48 hours. I just encountered this issue again this morning (Dec. 25th) hence the note. Thanks.
