Please HELP!

Customizations were working fine and now they are not. I believe it happened after I did the migrate custom pages. I receive this error when I go into system reports tab then custom reports:

Alert: Custom Page Management is not currently supported by the custom reports management engine at this time.

What can I do to fix this?? I have been working on this for two days now and I am having no luck..please if anyone knows..please help!!
