How to Fix Missing Add Web Part Button in SharePoint
Question details
The user is unable to add web parts because the blue plus sign button does not appear when editing a SharePoint page.

- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Editing a SharePoint page to insert new content or web parts.
- Observed behavior
- The blue plus sign button used for adding web parts is missing from the interface while the page is in edit mode.
Ensure you have clicked the 'Edit' button at the top right of your SharePoint page, and try refreshing your browser cache to rule out any temporary loading glitches.
Verify Modern Page Type and Edit Permissions
Ensure you are working on a modern SharePoint page and have sufficient access rights to modify the site.
The blue plus sign for web parts is an exclusive feature of modern SharePoint pages. Classic pages use a different interface. Additionally, you must have the correct site permissions to edit pages and add content.
Look at the layout of your page. If it features a traditional ribbon at the top similar to older Office applications, you are on a classic page, which does not support the modern blue plus button.
Click the gear icon (Settings) in the top right corner and select 'Site permissions'. Ensure your account has at least 'Edit' or 'Full Control' access.

Escalate to Your Microsoft 365 Administrator
If the page is modern and your permissions are correct, the issue might stem from backend site configurations requiring admin intervention.

Frequently Asked Questions
Why does my SharePoint page look different and lack the blue plus button?
You might be viewing a 'Classic' SharePoint page instead of a 'Modern' one. Classic pages rely on a ribbon menu at the top of the screen for inserting web parts, whereas Modern pages use the inline blue plus button.
Can a site owner disable my ability to add web parts?
Yes. If a site owner changes your permission level to 'Read' or restricts specific page editing capabilities, the Add Web Part button will disappear. You need 'Edit' or higher permissions to add web parts.
What should I do if the web part button disappears only on specific pages?
This often indicates a page-specific corruption or a customized page layout template that restricts web parts. Try creating a brand new modern page to see if the button appears there. If it does, the issue is isolated to the old page's configuration.
