Error on editing page containing profile edit control: The p

Hi,

I added a profile edit control onto a page, but now when I go to edit it again I get the following error:

The page cannot be displayed because an internal server error has occurred.

There are no errors occurring in the error log, and all other pages can be edited fine.

I have tried unpublishing and republishing, but without any other error information I don't know what else to try.

Thanks

Hayley
