W3 Total Cache causing problems

Hello.

I am encountering some problems with WordPress.
1. Ubermenu is not working, also it’s settings layout is all messed up.
2. No floating social bookmarks plugin is displaying the floating bar correctly.
3. Plugin icons and images are not being displayed in dashboard.

I had deleted W3 Total Cache earlier but recently reinstalled it. Upon reinstalling, Ubermenu and the floating bookmarks started displaying properly, as intended. But soon after the layout of the entire website messed up and I had to disable W3 Total Cache and the website went back to the way it way. I’ve tried a lot of things but couldn’t identify but now I think it might be something related to W3 Total Cache.

Any help will be very much appreciated.

Thanks! 🙂
