No errors. I’m getting a couple warnings about fonts that say “Resource interpreted as font but transferred with MIME type application/octet-stream.”
But I still get those warnings when I turn off the plugin, and the menus work fine.
I’m not sure what kind of settings you’re referring to. It’s not happening on any one page, it happens after you’ve clicked through two pages on the site. So if you land on a page, click a link in the sidebar, and click another link in the sidebar, the page you land on will have the problem, unless I turn off the plugin in which case all the pages look fine.
