Hi, i have getting these on a couple of pages on a episerver 5 site. The pages have been working fine but suddenly give the following exception without any code changes or deploys. I presume that the OnPageEditControl is something that has to do with episerver? What exactly does this control do? When i get the error i´m not loged in.

 Server Error in '/' Application.
Multiple controls with the same ID 'OnPageEditControl' were found. FindControl requires that controls have unique IDs.
