Custom plugin doesn't work properly

Hello.

I actually don't know if you can help me here, but I really hope you can. On my homepage: http://www.bloggerspoint.dk, I have a feed displaying the latest post. In the right side of the homepage under "MEST LÆSTE BLOGS I GÅR" (Most read blogs yesterday) it should display the most read Pro Site blogs from yesterday. The plugin has worked fine, but suddenly the toplist just disappeared alongside with "POPULÆRE BLOGS" (Popular bloggers). The site used to look like this: http://unitedbloggers.no with the toplist and popular blogs carousel.

I thought you maybe could see if something was wrong with the site or the plugin. I have tried to disable all plugins, but with no result. I can't find any recent changes that should have caused the problem. The custom plugin also uses the Popular post plugin, to get the most popular posts: https://wordpress.org/plugins/top-10/
