MVC Rights Management System Dwpro Project permissions button for no reason automatically disappear problem

The problem with the Missing permission button is modified as follows:

Cut the CONFIG. xml file in the Xmlconfig folder in the source file to the root directory and modify the file name to: App. Config (the key is that the suffix is not a "config")

Then change the source file in Web. config to: App. config will work as follows:

The XML configuration file must be modified to the config suffix, if it is an XML file can be downloaded directly, it is not safe

Others click on the URL plus this file name path so that the configuration file download, horror Ah!

Now this modifies the double benefit, the permission question both solves, the security question also solves!
