Problem Statement: This page allows a limit of 200 controls, and that limit has been exceeded in SharePoint

Solution:

1.    Browse to the Web application “C:\inetpub\wwwroot\wss\VirtualDirectories\”

2.    open webapplication in question

3.    open web.config for that web application

4.    Find the tag below in the web.config

<SafeMode MaxControls="200" CallStack="false" DirectFileDependencies="10" TotalFileDependencies="250" AllowPageLevelTrace="false">
