I'm unable to open or delete messages in my yahoo email account? How can I fix this?

I'm able to view messages in the preview pane, but unable to open the message or delete. I'm also unable to open the help box or other areas om the yahoo mail page. Any ideas on how this can be fixed would be appreciated.

Go into messages, hit the ones that you want to delete and that should do it, I did run into a similar problem when I updated my yahoo account so I went back to the old one
