I know, I know. But we still have users who are using it (several old company guidelines).

I am pretty sure that when we set our site live that it was viewable with internet explorer (11).
But now, the site is blank.
We have https enforced and run 2.4.0.beta10 - which will turn 11 over the weekend.

On my testsite which went from beta9 to 11 and which does not have https enabled, I get a hint that my browser is too old.

On our live-site the page comes blank and in the logs I see an error

This was fixed a few days ago, so the problem should be resolved as soon as you update your site :slight_smile:

But also, note that we will be dropping IE11 support in June:
