Bug on mobile

Hi,

Since I have installed your plugin I have a strange issue on my website (theme 15zine).

The post sidebar is different on desktop and mobile display. The mobile always displays the default website sidebar for all posts. I have tried to delete your plugin but the issue is still here.

Please, can you tell me what files to delete / change to completely remove your plugin.

Thank you.
