Hi there. Full disclosure-a friend built my website and I'm a computer moron. After the last plugin update my categories disappeared and in place was an error message reading 'fatal error:  operator not supported for strings in' and then something about line 117 and categoryicons.php. The error message was a link that led to the first of the 8 categories that should be on the page. My friend who built the site was able to get all 8 categories to come back but not the icons, only text links. I don't know for sure it was the update, but it was working fine earlier that day and then not working immediately after. thanks.
