When creating a new site collection using PowerShell:
New-SPSite $siteCollUrl -Name $siteCollName -Template $template -OwnerAlias $siteCollAdmin –Language $siteCollLanguage
you might get an exception:
New-SPSite : The URL '/sites/sitecollname/' is invalid. It may contain illegal characters, or be too long.
The problem is caused by the trailing slash in the new site collection URL. It should be removed.
