Is there any additional information in the browser console?

Unfortunately there is no additional information in the browser console.

In that case, I don’t know how to debug this, sorry :/

Hallo Lucas, thank you very mych for your help :-) The browser console of my PC at the office did not show any extra information, but the console on my PC at home does. This is what I get:

Hm, that might be a problem with loading MathJax, though it’s documented to still support IE11… are you maybe using an emulation mode / compatibility mode?

No, wait, we already include the <meta> tag which the MathJax docs recommend to force IE standards mode, so that probably isn’t it.

Can you try in the browser console if MathJax is a real object? (Starts with { version: "3.0.0" on my system.) Or if there are any earlier errors that look related to MathJax, maybe?

I tried opening the linked query.wikidata.org page in IE and it sometimes works and sometimes doesn't. (The ascleiden.nl page seems to consistently not work but maybe I just didn't refresh enough times)

The full contents of the console for me is:

The TypeError is the only bit which only appears when it doesn't work, so the other lines don't seem relevant.

I can't work out whether MathJax is an object or not. I can't find a way to type in the console...

The clearCache() call looks like MathJax.startup.output.clearCache(), so if MathJax wasn’t an object, I would expect the error to mention startup, not clearCache. Strange.

IE11 is no longer supported.

It’s no longer supported by MediaWiki, but I’m not aware of that decision including the WDQS UI as well (which is a totally different tech stack).

Fair enough. The decision was partly based on usage falling below 0.1%. It's probably even lower amongst WDQS users who are likely more technical, so I'd recommend you do the same :)

Indeed, I filed T334876: Drop IE11 / ES5 support from the Wikidata Query Service UI for it.
