kareemsayeed on "[Plugin: Q2W3 Fixed Widget (Sticky Widget)] Love the plugin but not working on new template"

Works great on postmemes.com but on my new site: postmemes.com/videos it jumps from right to left once I start scrolling. I disabled the plugin but let me know if I should -re-enable in order for you to debug the problem. Thank you!
