SharePoint Online: Copy pages WITH the web parts

If you have a bunch of web parts on a page in SharePoint Online, none of the standard copy actions actually brings the web parts with a web part page.  But if you go to the old Site Content and Structure by adding to the site collection url:

     https://yourcompany.sharepoint.com/_layouts/sitemanager.aspx

You can then copy pages and they'll bring along all of their web parts.

Remove User Permissions: You have chosen to delete too many groups at once. Select fewer groups and try again.

If you run into the issue of removing many individual users (particularly if you're using item level security this can happen quickly), you can only delete a maximum of 500 users at a time.

If you have more than that, you basically have two options:

1)  Click each checkbox individually and remove in groups until you get under 500.
2)  Open up Chrome, press F12, run the following script in the console:

var i = 0;
$('input:checkbox').each(function () {  
   $(this).attr('checked', true);
   i++;
 
   if (i >= 475)
   {
 return false;
   }
  });

This will select the first 475 users, and from there you can remove the user permissions.
