i use Chrome and notscripts, recently get a failure to authorize with stackexchange and cannot chat with a moderator anymore. http://chat.stackexchange.com/help Is this a problem with the recent update to Chrome? Clearing or resetting HTML5 as suggested does not help, how to do this manually? Fails in Incognito mode also. How do I sort this out, thanks. Chrome version 13.0.782.107 m ![enter image description here][1] ![enter image description here][3] . If I disable Notscripts, still not working. Clean re-installed Chrome Error persists, Looked in my local storage folder and this file was in there "http_chat.stackexchange.com_0.localstorage" ![enter image description here][2] SOLUTION: it appears the extension "NotScripts" is no longer compatible with the new Chrome update, even if I don't install it but do copy my old preferences file to the new installation, it causes this issue, so something notscripts stores in preferences can cause the issue. Case Closed. . [1]: https://i.sstatic.net/w6L80.png [2]: https://i.sstatic.net/1QfRJ.png [3]: https://i.sstatic.net/PXqpA.png
