On the SE.com site, affecting my global Filtered Questions, if I attempt to click the edit link, the JavaScript console reports an error:

TypeError: $.browser is undefined[Learn More] jquery.autocomplete.min.js:11:1270

Same error on Firefox and Safari running on MacOS.

On Chrome latest version under Windows 7 the error is:

jquery.autocomplete.min.js:11 Uncaught TypeError: Cannot read property 'opera' of undefined(…)

  • Same when trying to add tags to new filter, at least with Chrome. Dec 14, 2016 at 11:48

This was caused by an outdated jQuery autocomplete plugin - we've updated jQuery but not the plugin, which started breaking.

We have now updated the plugin, so the page is back in operating condition.
