When the plugin it’s active the content on my site doesn’t load

Hi, compliments for this plugin, it’s awesome.
However I have a big problem when I activate the plugin: the content on my site (posts, images, videos) doesn’t load. The homepage works fine, but when I click on a post / image/ video, the content is not showed and only the main menu keeps visible.
The chrome console shows me “internal server error 500”.
I currently use Novavideo theme 2.2.2
Is there any way to fix this?
