We’re having issues with the calendar not displaying in IE 9 and IE 10, but working fine in other browsers.

We have the exact same environment setup on production and staging; the only difference is that production is running WP 4.1.1 and staging is running 4.1. The calendar works fine on staging but not on production. Hosting is at WPEngine and all necessary options for hosting EE have previously been requested/enabled by WPE.

Staging calendar (works fine): stonece.staging.wpengine.com/calendar
Production calendar (doesn’t work): stonece.com/calendar

Both are running EE3.1.36.6.P

Right now both are running calendar 2.2.4.p but we have also tried 2.2.6.p and 2.2.3.DEV

Is there something in WP 4.1.1 that would cause this issue?

Hi, the staging site for WP Engine does not running caching. That is one thing to be aware of.

Could you go ahead and update the staging site to WP 4.1.1 and let us know if the issue persists?

Also, the old version of the calendar isn’t needed since the current release includes those fixes. Please be sure that you are using the updated (latest) version.

Hi,

We updated staging to 4.1.1 and the calendar still works there, but doesn’t work on the live site.

WPEngine has turned off caching for /calendar/ on the live site, so it shouldn’t be the caching causing it.

The following are our cache exemptions:
/events/
/registration-checkout/
/transactions/
/thank-you/
/registration-cancelled/
/calendar/

What else can we try?

Hi,

Are you running HTTPS? If so is it running only in the admin or only on the front end or is it HTTP for both?

We had another query recently where the calendar failed in IE and it was because of the admin area running HTTPS but the front end wasn’t. AJAX on the front end of WP uses the admin-ajax.php file so if the front end is HTTP, and the admin is HTTPS some browsers (hello IE!) reject the request, effectively breaking the calendar.

Hi Tyler,

Using IE 11 emulating IE9 + 10 I had no issues with the Calendar on the live site – http://take.ms/LQXrM

Does the Calendar not load at all for you or is it the events themselves not loading?
