Menu dropdown broken

Hi,

Just installed the theme, still very much in the process of setting up. Loving it so far.

My main menu suddenly had all its dropdowns broken: http://building.mediumutm.ca/ They just display blank. You can still see the correct target when you hover over them, but they display nothing. I’ve tried this in three browsers now.

The only thing I was doing that might have changed it was the header alignment. I entered 20px. But I’ve undone it now, cleared cache, etc, and no change. I also deactivated the last few plugins I had installed, no luck.

Any thoughts?

Thanks! I’ve been playing around with these settings, but there’s still some unusual behaviour. It seems to be when looking a parent category archive page, and clicking the dropdown for that category, you get the background and link colour being the same. Here it is with some ridiculous colours for testing:

On the same category as the dropdown you’re looking at, both text and background of the dropdown are the same colour. What might cause this?

Fixed by switching to a different theme and back.
