SP2019 On-Prem: Error message on creating a site collection

Jens Friedrich 201

Hello,

my "normal" users should be able to create a site collection.

This works normally via your personal homepage (click on "SharePoint" on the top left corner and than "+ New website"). Whether I'll try to create a team or a communication website, I'm getting the following error message (even as Administrator) starting the creation process:
"Couldn't create the site, please go back and try again."

How can I resolve this error?

It's a strange thing that it works via Central administration with a farm admin account.
Option "Allow users to create site collections in defined URL namespaces" is set to "On" in the Self Site Creations
Option "Show the Create site command to users who have permission to create sites" is activated
Option "This web application" is set to "http://[Domain]/websites".

Based on your description, I understand that you cannot create a new site collection in the SharePoint server 2019 home page with correct settings.

Per my test, I could not reproduce the issue. As a workaround, you could try to use following PowerShell to check if users can create a new site collection.

New-SPSite https://webApp/sites/test -OwnerAlias "DOMAIN\JDoe" -Language 1033 -Template STS#0

This PowerShell creates an English site collection at https://<site name>/sites/test that is owned by user DOMAIN\Jdow.

@Emily Du-MSFT I know that it works with the PowerShell cmdlet. But the "normal" user has neither a PowerShell environment nor is he/she familiar with the syntax of any cmdlet.
That's why they should be able to create a site collection via SharePoint frontend GUI but without any farm administrative rights.

@Jens Friedrich

Have you make any update recently? Whether this issue persistent or occurs recently?

In which web application did you create the site collection in the central administration? Is it in the same web application as the site collection created through UI?

Please go to central administration -> Manage web applications -> Select the web application where site collections are stored -> User Permissions in the ribbon -> Make sure that you have select all permissions.

And go to central administration -> Manage web applications -> Select the web application where site collections are stored -> User Policy in the ribbon -> Check whether have Deny permission.

@Emily Du-MSFT
It's just an out-of-the-box SharePoint including all current SharePoint updates.

It's the same web application as through the UI or the PowerShell cmdlet.

All permissions are set in the User Permissions dialog. Full access is granted to the "normal" user in the User Policy dialog.

You mentioned that this is an out-of-the-box SharePoint including all current SharePoint updates, does it mean that SharePoint has installed the latest CU?

@Emily Du-MSFT It's a persistent problem.

Out- of- the- box- SharePoint means a clean Windows Server, MSSQL Server, Share Point installation and configuration with all the latest official Microsoft updates and without any customization except granting the rights for creating new websites yet.
