It's most likely a bug in a gadget that you're using.

Can you please open the JavaScript console and tell me whether you see any errors there?

Hmm, it even loads for me here after enabling all gadgets.

Please follow https://www.mediawiki.org/wiki/Help:Locating_broken_scripts

"User:Amalthea_(bot)/userhighlighter.js/sysop.js Failed to load resource: the server responded with a status of 404 ()" seems error.

"User:Amalthea_(bot)/userhighlighter.js/sysop.js removal didn't help but blanking entire JS seems to solve the issue

Cool... kind of.

If you want these things back, I suggest adding them one by one and checking which of them breaks Content Translation.

Thanks!
