Dear IBN.,

Thank you for reaching out

Sorry for not making things clear enough in my first email. The scripts requires PowerShell 7 and PnP powershell module. Please follow below steps to connect.

• Install PowerShell 7: click here --->>Installing PowerShell on Windows - PowerShell | Microsoft Learn

Install PnP PowerShell Module with command:

Install-Module PnP.PowerShell

• Register your PnP App:

Register-PnPEntraIDAppForInteractiveLogin -ApplicationName "PnP Rocks" -Tenant [yourtenant].onmicrosoft.com -Interactive

• Connect to SharePoint:

Connect-PnPOnline [yourtenant].sharepoint.com -Interactive -ClientId <client id of your Entra ID Application Registration>

• Update the logo

Set-PnPWeb -SiteLogoUrl "https://YourTenantName.sharepoint.com/sites/YourSite/SiteAssets/YourLogo.png"

If none of these steps resolve the issue, feel free to reach out. I’ll be happy to assist further.

Best regards,

Dear IBN.,

Thank you for reaching out regarding the issue you're experiencing with updating the Site Logo Thumbnail. I understand how frustrating this can be, especially since the process worked on your other sites. Let me offer a few suggestions to help resolve the issue:

1. Clear Browser Cache: Sometimes, the browser cache can interfere with changes being saved. I recommend clearing your cache or trying to upload the logo using an incognito/private browsing window.
2. Check Image Format and Size: Please ensure the image is in a supported format (such as JPEG or PNG) and that it meets the size requirements for site logos. You might also try uploading a smaller file size to see if that helps.
3. *Verify Permissions: Ensure you have the correct permissions to make changes to the site. If the permissions are not sufficient, the changes might not save properly.
4. Modern Experience Requirement: The "Change the Look" feature is designed for modern SharePoint sites. If your site is using the classic experience, you may need to update the logo from the classic settings page instead.
5. PowerShell Alternative: If the above steps do not resolve the issue, you could try updating the logo via PowerShell. Here’s a sample script:

# Connect to SharePoint  
Connect-PnPOnline -Url [https://YourTenantName.sharepoint.com/sites/YourSite](https://yourtenantname.sharepoint.com/sites/YourSite "yourtenantname.sharepoint.com") -UseWebLogin

# Update the logo  
Set-PnPWeb -SiteLogoUrl "[https://YourTenantName.sharepoint.com/sites/YourSite/SiteAssets/YourLogo.png"](https://yourtenantname.sharepoint.com/sites/YourSite/SiteAssets/YourLogo.png%22 "yourtenantname.sharepoint.com")  

If none of these steps resolve the issue, feel free to reach out. I’ll be happy to assist further.
