#26438 closed defect (bug) (fixed)

Theme Customizer is non-functional in IE11

Reported by: celloexpressions's profile celloexpressions Owned by: nacin's profile nacin
Milestone: 3.8 Priority: highest omg bbq
Severity: blocker Version: 3.8
Component: Customize Keywords: has-patch
Focuses: Cc:


Changing a control throws a JS error, and thus prevents the preview from updating and or the save button from becoming enabled.

The error is invalid calling object on line 265 of custommize-base.js.

Doesn't seem to affect Chrome or Firefox.

Introduced in [26548].

We haven't updated Underscore.js since 1.4.4. I haven't seen anything in the logs to suggest that 1.5.2's version of _.isEqual would fix this.

At worst we can revert [26548] and save it for 3.9. I would rather not have that optimization in, if it causes problems. If it's caused at least one issue, there's bound to be another.

I found and some other pages. should be replaced by This should be also reported upstream.

Seeing also an issue in IE 8 for hasOwnPropertery, see

So +1 for a revert and review this again for 3.9, since the same code exists in 1.4.4 and us used by the media modal where _.isEqual it works.

In 26702:

Customizer: Revert [26548], removing _.isEqual() for proper object comparison.

This broke the customizer in IE 11, with possibly other side effects. Revisit in 3.9.

Also reverts [26632].

see #26061 (reopens), fixes #26438.

Header image changing now works fine.
Changing header text color doesn't live preview as it does on Chrome.

  • Resolution set to fixed

works for me in IE 11 with Twenty Fourteen.

Please open a new ticket if you think this is a bug in 3.8, but with some more Infos, like IE version, theme name and so on.

Re-closing since the reported issue was fixed.
