Issue with admin user editing content block
Is there any reasons why a user with admin level can not edit any content of the webpage?

First of all you have to check your page permissions. Go to Pages, select Actions, then Permissions, click Break inheritance and check who can edit/create/modify/delete pages.
Finally it is important to check your web configuration of the project. Go to your project in Visual Studio, select web.config and check whether forth of the assemblies present in project.
