You can follow the procedure below to fix the issue.

*** Please note that Microsoft is aware of the issue, but as yet don’t have a resolution for it.
However, with a bit of PowerShell you can solve the problem.

You will need….
– To be an Administrator on the O365 subscription

– Windows PowerShell – (Download: https://www.microsoft.com/en-gb/download/details.aspx?id=42554)

– SharePoint Online Management Shell – (Download: https://www.microsoft.com/en-gb/download/details.aspx?id=35588)

– SharePoint Online Client Components SDK (Download: http://www.microsoft.com/en-us/download/details.aspx?id=42038)

After you have your PowerShell tools installed, follow these steps:

1. Open Windows PowerShell in Administrator mode and execute the script

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

2. Open SharePoint Online Management Shell in Administrator mode and execute the script

$clientDll = [System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SharePoint.Client”)
$runtimeDll = [System.Reflection.Assembly]::LoadWithPartialName(“Microsoft.SharePoint.Client.Runtime”)


$url = “https://your site collection url”
This is the URL to your SharePoint Online (O365) tenancy. ie = https://xxxxxxxx.sharepoint.com/


$cred = get-credential

$clientContext = New-Object Microsoft.SharePoint.Client.ClientContext($url)
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($cred.username, $cred.password)
$clientContext.Credentials = $credentials

if (!$clientContext.ServerObjectIsNull.Value)
{
Write-Host “Connected to SharePoint site: ‘$Url'” -ForegroundColor Green
}

$clientContext.Site.Features.Add(‘e995e28b-9ba8-4668-9933-cf5c146d7a9f’,$true,[Microsoft.SharePoint.Client.FeatureDefinitionScope]::None)

$clientContext.ExecuteQuery()

Now go back to your SharePoint Online tenancy and try again to create a new site using a custom template.
