Version: 4.1.3 Reporter: James Catt —
Under IE11 (I haven’t tested earlier versions), I’m seeing the following on entry publish/edit CP pages:
I suspect this is probably just a cascading problem stemming from JS execution being halted by the error below. Either way this makes it impossible for IE users to create/edit entries.
I think this might be a recent bug because I had two people both report it just today (upgraded to 4.1.3 a couple of days ago).
Here are the console errors I’m seeing:
