When you want to copy or export profile(s) and you get an error that it can't perform the action, it is not telling you in which profile the error occurred. Even when you resolved all issue with the "Troubleshoot" in Customized pages and still get errors, you need to go through all customized profiles (or delete them 1 by 1) to find out where the error came from.

So send the profile name(s) in where the errors are found in the error message.
