Over the past two days I have been experiencing various problems using SE sites - the first I noticed is that my chat wouldn't work even though I was logged in ("You need 20 reputation to talk here") when I was clearly logged in to SuperUser. Also on SU (as well as security.SE) I have not been able to upvote, add comments, or favorite questions.

I asked if anyone else on in the chat (once I was able) was having the same problems and the user Carl B said he was having the same problems if that helps to narrow down any possibilities. I have rebooted and cleared my browser cache as well, yet I am still not able to up/downvote / comment / favorite.

What could be causing this, could it be something I have done or is it on the SE side?

Edit: Also, the past two questions I have asked (this one and one on Security.SE) it has asked me to enter in a captcha. Not sure if that's relevant, but I figured I would add this. I can also not view up/down votes on questions, and when I click the StackExchange drop-down menu in the upper left it takes me to stackexchange.com

This is what the error console shows enter image description here


Per JavaScript on whole site is broken in IE (9 or less) because of stub.js:

We are trying to block a scraper that is scraping against our terms & conditions.

This bug was an unforeseen consequence of trying to ban them client side - not realizing that atob is not supported by IE 7/8/9 (and 10 in 7/8/9 mode).

I am reverting the change and deploying as we speak.

Things should be back to normal soon-ish.
