SharePoint sub site creation fails for "Team Site (classic experience)" with german language

Question

Hello,

when I try to create a new sub site, for any Site Collection, under "Site contents -> Subsites -> New -> Subsite" it fails when German as language is selected.
If I choose English, the creation succeeds. The problem only occurs for the Team site (classic experience) template (screenshot 1).

I get an error page with a message like that: "Can not open "Homepage.aspx": File or directory with this name does not exist" (translated from screenshot 2).

This concerns SharePoint Online. I think it is a global problem, because it happened on a customers SharePoint too. The issue occurs since first november 2021.

Was there a recent change or deprecation that could cause this?

As a workaround I currently create subsites only in English.

I appreciate any help on this.
Thanks,

Oliver.

Answer 2

Hi @Oliver K ,

Is there any progress on this issue? Per my test, i could create subsite with german language.

You could try to use the following PnP PowerShell commands to create subsite with german language.

#Config Variables  
$SiteCollURL = "https://tenant.sharepoint.com"  
$SiteTitle = "xxx"  
$SiteURL = "xxx"  
$Description = "xxxxx"  
$Locale = 1031 #German  
$Template = "STS#0" #Team site  
   
#Get Credentials to connect  
$Cred = Get-Credential  
   
Try {  
    #Connect to PNP Online  
    Connect-PnPOnline -Url $SiteCollURL -Credentials $Cred  
   
    #sharepoint online powershell create subsite  
    New-PnPWeb -Title $SiteTitle -Url $SiteURL -Description $Description -Locale $Locale -Template $Template -ErrorAction Stop  
    Write-host "Site '$SiteTitle' Created Successfully!" -f Green  
}  
catch {  
    write-host "Error: $($_.Exception.Message)" -foregroundcolor Red  
}
