I have an Umbraco 4.5.1 website and I am getting the following error when I try to make changes to the permissions on a node:
Multiple controls with the same ID '1_a' were found. FindControl requires that controls have unique IDs.
I remember having something like this before and it was because of the Google Analytics package, well this package was installed before upgrading to 4.5.1 but I have since deleted the DLL's associated with it which I though resolved the issue before. Does anyone know what else it could be or what I can do to fix it?
Thanks again for the response, I have now added what you said to the pages section so it now looks as follows but this does not appear to have made any difference:
Hi trfletch, did you solve this? I had this problem tomorrow. Restarted the computer and it worked, but I don't think doing this everyday is an option.

Did you manually upgrade this website to .NET 4.0?
If so, check if <pages clientIDMode="AutoID"> is set to AutoId.
Hi,
Thanks for the response, where do I find that value?
Do a ctrl+f on "<pages" in the web.config file.

<pages enableEventValidation="false" clientIDMode="AutoID">

If you see this when editing a node in the BackOffice, here's some things to try.
