Username: @SarahTehCatThis is a recurring bug with users not being able to log in, due to inconsistent state between CentralAuth and local wikis (specifically the local user table row missing in the latter).

====For user which this affects
A possible fix: Enter your username at [[https://test.wikipedia.org/wiki/Special:CentralAuth|testwiki:Special:CentralAuth]]. Look for text of form `Could not find local user data for username@X`, where `username` is your name and `X` is the name of a wiki. Try to log in at that wiki. For example, if `X` is `bewiki` then enter `be:` in the search box to get to the [[https://be.wikipedia.org/wiki/|be:]] wiki, or look for the wiki at [[https://en.wikipedia.org/wiki/Special:SiteMatrix|Special:SiteMatrix]]. The language may be foreign but the login link should be at the top right or top left, or you can enter `Special:UserLogin` in the search box.
18:57:07 <SarahTehCat> My issue is this: every time I log in, I get an error page that's entirely blank except for the error message: "Exception encountered, of type "Exception" "
18:57:25 <SarahTehCat> I've tried it in Incognito Mode in Chrome, and I've even done it in safe mode in Firefox.
18:57:57 <SarahTehCat> I copy/pasted the password, so I'm 100% sure my login information is correct, too.
18:58:20 <SarahTehCat> This only started within the last week or so

18:59:49 <SarahTehCat> Note that Firefox is in safe mode in that screenshot :)
19:01:51 <SarahTehCat> Not sure if it's relevant, but I'm running Ubuntu 15.04 on a Dell Inspiron N5010 laptop. Firefox is set to auto-update too, so I have the latest version.
19:35:03 <+Josve05a> SarahTehCat: Do you have cookies turned off whie in secure-mode?
19:35:51 <SarahTehCat> Also, one sec, lemme check
19:36:05 <SarahTehCat> ...How do I check? Lol.

19:37:12 <SarahTehCat> Okay, thanks
19:39:14 <SarahTehCat> Okay, I just disabled cookies.
19:39:21 <SarahTehCat> Should I remove all existing cookies as well?
