“Add users to a SharePoint group” Disabled
January 11, 2012 Leave a Comment
In researching this error, the posted answers had to do with the site being created by code – and the solution was a change in the code.

However, it wasn’t my code creating the sites, but the migration tool I was using. Changing their code wasn’t an option. So if you have a site where the “Add users to a SharePoint group” drop-down is disabled, you can solve this in two ways.
Using the GUI:
Site Actions > Site Permissions – go into each group you want available in the drop down and make it the default group -leaving for last the actual group you want to make the default.

PowerShell Script:
Add all of the groups desired to be part of the dropdown – leaving the actual group you want to make the default last.
cls
$snapIn = Get-PSSnapin | where-object {$_.Name -eq "Microsoft.SharePoint.PowerShell"}
if($snapIn -eq $null) {
Add-PsSnapin Microsoft.SharePoint.PowerShell
}
$Web=Get-SPweb https://WEBAPP/sites/SITE/SUBSITE
$Web.AssociatedMemberGroup=$Web.SiteGroups["SITENAME Contributors"]
$Web.AssociatedMemberGroup=$Web.SiteGroups["SITENAME Manager"]
$Web.AssociatedMemberGroup=$Web.SiteGroups["SITENAME CUSTOM Group"]
$Web.AssociatedMemberGroup=$Web.SiteGroups["SITENAME Visitors"]
$Web.update()
$Web.dispose()
