Thanks! I realise the uncategorized menu only appears on my custom category page http://kanjilight.xyz/landscapes/ so I guess it displays the menu differently somehow.

I have attached a screenshot of portrait view on ipad and marked in red the space. This is only for that landscape category page I made – the others work fine.

And can you check on mobile the the accordian on that page – it always displays open to begin with on mobile, but not on tablet or desktop!

Will be leaving you a very positive review on themeforest!
