I found that the error was caused by removing any of these modules:

<add version="4.1.1405.0" name="Blogs" />
<add version="4.1.1405.0" name="Events" />
<add version="4.1.1405.0" name="Libraries" />
<add version="4.1.1405.0" name="Lists" />
<add version="4.1.1405.0" name="Analytics" />
<add version="4.1.1405.0" name="Scheduling" />
<add version="4.1.1405.0" name="Publishing" />
<add version="4.1.1405.0" name="Newsletters" />
<add version="4.1.1405.0" name="GenericContent" />
<add version="4.1.1405.0" name="ControlTemplates" />

(Note: All the corresponding backend pages were removed and the site works fine until you click on "create a page")
