Go to the page itself in your web browser and make sure you have full owner permissions of the page and site.


Override the checkout next to "Site Actions" by clicking on Page -> Override Checkout and it should work.

If NOT: The default.aspx masterpage is probably not in the "Pages" folder. Try opening the below URL into SP Designer (take the "/Pages" out):


And this should work.

  • Override checkout - "Cannot Complete this action The file "Pages/default.aspx" is not checked out"

  • SP Designer - "The folder name is not valid"

You can try to clear cache of a SharePoint designer from the machine you are opening it.

The cache is composed of these 2 folders:

  1. %APPDATA%\Microsoft\Web Server Extensions\Cache
  2. %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache

Just delete the content of these folders.

  • its not working for me ,
