Yea, I’m experiencing this even when resizing my browser down to mobile size.
It seems there’s a javascript error somewhere, because the navigation isn’t rendering the dropdown arrow, or the effect when it drops down.
Can you try deactivating any plugins you have and see if the problem persists?
If not, activate each plugin one by one until you find the culprit.
Let me know what you find out 🙂
Also – I love your website, it looks great!
