I am working on an Enterprise wiki site collection , and i found this strange behavior:-

  • Currently we have our home page URL as /Welcome.aspx

  • Now if I edit the home page properties and i change the welcome page name to an existing name let say WelcomeNew.aspx, I will get the following error :-

Sorry, something went wrong The specified name is already in use.

The document or folder name was not changed. To change the name to a different value, close this dialog and edit the properties of the document or folder.

  • Now if I refresh the error page I will get the following message:-

Sorry, something went wrong The file Pages/welcome.aspx has been modified by i:0#.w|tdmgroup\administrator on 29 Apr 2015 16:22:54 +0100. Technical Details

Then if I navigate to my site collection I will find that the welcome page became WelocmeNew.aspx instead of Welcome.aspx can anyone advice on this ?

  • now Welcome.aspx will still there, but the WelcomeNew.aspx will became the new home page,, now if i go to welcome.aspx and i set it as the home page everything will work fine,, but not sure why this is happening,, i mean if you rename ur home page to an existing name , the existing name wiki page will became the home page !!!

1 Answer 1


Here is what I found

  1. You change home page to new name
  2. SharePoint set site home page = new name
  3. Tries to change the name of actual file

I believe step#2 should have been done after #3 or there should be a rollback mechanism

  • so it is a bug in sharepoint what do u think ?

  • but it is good that the welcome.aspx page content did not got replaced by the welcomeNew.aspx or vice versa !!!
