Just as a side note, it is usually very helpful if you include a link to your site when you post a question.
Try adding this CSS to the Custom CSS option (Appearance > Theme Options > Design Options, scroll down to the bottom):
select.tinynav option:last-child {
display: none;
}
Did anyone get this to work? “Navigation” still shows up on my iPhone.
Did you try adding the above CSS? Can you share a link to your site?
I have the same error. The CSS above works in my browswer on my desktop when i shrink it down, but on my iPhone, Navigation still shows. Not too big a deal as it just goes back to my main page.
Can you post a link to your site where this is occurring, nirsound? That will help us to be able to resolve this error for you 🙂
