Hi @Mohamed Saleh

The error: The 'DelayActivateTemplateBinding' attribute is not allowed.indicates that SharePoint is failing to validate a feature definition during activation. This is more consistent with a feature/schema validation issue than with the general absence of site-template support.

Because the same behavior occurs with:

Multiple site collections

Newly created Team Sites

Newly created Project Sites

Both saving the site as a template and activating the generated solution

I would recommend checking the SPSE farm before troubleshooting the individual site:

Verify the exact SPSE build with: (Get-SPFarm).BuildVersion
Confirm that all SharePoint servers are running the same build/CU.
Run Get-SPProduct -Local on the SharePoint servers and check for any pending configuration or installation issues.

If the farm is fully patched and configured, and the same error can be reproduced on a newly created site using Microsoft-provided functionality, I would recommend to contact Microsoft Support.

Hi @Jayden-P ,

Thanks for your reply.

Below is the output of (Get-SPFarm).BuildVersion:

Major Minor Build Revision 16 0 19725 20522

This is a single-server testing environment, and it has been updated to the latest available SharePoint Server Subscription Edition (SPSE) release.

Below is the output of Get-SPProduct -Local:

ProductName Required Missing Servers ----------- -------- ------- ------- Language Pack for SharePoin... True {} Language Pack for SharePoin... True {} Microsoft SharePoint Server... True {}

There are no missing components or pending installation/configuration issues reported by Get-SPProduct -Local.

Unfortunately, I do not have a SharePoint Subscription Edition environment available to reproduce and investigate this behavior further.

I would recommend opening a Microsoft Support ticket so they can take a look at your environment. I apologize for not being able to solve this directly for you.
