Issue after uninstall.

Hello.
I have had an issue after uninstall WP Super Cache. I already read “Other Notes” and did every process well. It seemed work fine, but I found two buttons on top of the page do not work properly. They just jump to home page. Web site link is below.

If you click PS and PC on top of the page then you will find they jump to home page.
