Thank you Lara. I found the arrow, finally. I had, in Internet Explorer 11, internet options, accessibility, activated the “Ignore font styles in webpages” in order to make Times New Roman turn into Arial on newspaper sites. Apparently this option rendered the arrows invisible.
Now if I can only figure out how to put a search box in the header of the home page…I don’t seem to have access to the php files for my website, which is has the Responsive theme.
