I was having several problems including dead :Customize This Page" links. Also links to send a private message and add a comment or write in the newsfeed. Also slide show was stuck on first slide. Once I deactivated the newsfeed everything else worked. Wish there was a fix. I would like to use newsfeed as well.
after that press disable java and try to solve what its happend
sometimes customize bars some jave codes inserted do that
so try to figure it out what happend
good luck
