JQuery error during load "Failed to execute query: '*,:x' is not a valid selector."
jquery
Solution
I've found this jQuery bug ticket that seems like what you're experiencing, another one on StackOverflow describing the problem and a longer discussion about it on another jQuery bug ticket.
Although, it seems like it's not tagged as a bug as it's jQuery's internal error checking/exceptions being thrown.
As the comment by jQuery team describes:
Resolution set to notabug
Don't break on caught exceptions. We caught it because we expected it.
Problem
I am trying to debug an application and I can't start because I am getting an error as the browser is loading jquery 2.1.0. The error is on line 1210 of the unminified version ``` div.querySelectorAll("*,:x"); ``` and I am getting the error in the title. I am using Chrome version 32.
