How to Fix SharePoint Subsite Requiring Parent Site Collection Access
Question details
Users with access only to a SharePoint subsite may suddenly be unable to open it unless they also receive read access to the parent site collection, and need to determine whether permission inheritance or unique permissions caused the issue.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- A SharePoint user with subsite-only access tries to open a subsite but is blocked unless the parent site collection also grants read access.
- Observed behavior
- The subsite no longer opens for users unless they also receive read access to the parent site collection, suggesting a permission inheritance or unique permission change.
Before troubleshooting, confirm with a site owner or SharePoint administrator whether the subsite permissions were recently changed, and note whether the subsite is set to inherit permissions from its parent or use unique permissions.
Check Whether the SharePoint Subsite Uses Unique or Inherited Permissions
Use this first to identify whether the subsite has accidentally inherited restrictive permissions from the parent site collection instead of keeping its own unique permissions.
SharePoint subsites can either inherit permissions from the parent site or use unique permissions. If a subsite switches from unique permissions to inherited permissions, users who only have access to the subsite may be blocked until they also receive read access to the parent site collection.
Sign in to SharePoint as a site owner or administrator, open the affected subsite, and select Settings gear > Site permissions or Site settings.
Under Permissions, look for the permission inheritance option. If you see 'Stop inheriting permissions', the subsite currently uses unique permissions. If you see 'Delete unique permissions', it is inheriting from the parent.
Open the parent site collection permissions and confirm whether affected users have Read access or no access at the parent level.
If the subsite should use unique permissions, select Stop inheriting permissions, grant the required users or groups access to the subsite, and remove the extra parent read access if it was added only as a workaround.
Test the Behavior for Affected Users and Other Site Collections
Use this to confirm whether the issue is limited to one subsite, one user group, or a wider SharePoint permission configuration change.
Keep Working with WPS Office While Resolving SharePoint Permissions
SharePoint permission behavior is managed by Microsoft SharePoint and cannot be changed from WPS Office. For daily document tasks, WPS Office is a free, lightweight Microsoft Office alternative that opens and saves Word, Excel, and PowerPoint files with high compatibility.
- 1. Download WPS Office: Go to the WPS Office download page and download the free installer for your Windows, macOS, Android, or iOS device.
- 2. Open documents saved from SharePoint: Launch WPS Office and open the .docx, .xlsx, or .pptx file that you have permission to download from SharePoint.
- 3. Edit and save in Microsoft Office format: Make your edits in WPS Office and save the file in the original Microsoft Office format to maintain compatibility with SharePoint document libraries.
Frequently Asked Questions
Why does a SharePoint subsite suddenly require access to the parent site collection?
This usually happens when the subsite is configured to inherit permissions from the parent site collection instead of using its own unique permissions. SharePoint then requires users to have parent site access before they can open the subsite.
How can I check whether a SharePoint subsite uses unique or inherited permissions?
Sign in as a site owner or administrator, open the subsite, go to Site permissions, and look for the permission inheritance option. If it shows 'Stop inheriting permissions', the subsite uses unique permissions. If it shows 'Delete unique permissions', it is inheriting from the parent.
How do I restore unique permissions on a SharePoint subsite?
Open the subsite as a site owner, go to Site permissions, select Stop inheriting permissions, and then grant the appropriate users or SharePoint groups access to the subsite.
Is this issue caused by WPS Office?
No. This is a permission configuration issue in Microsoft SharePoint. WPS Office does not control SharePoint permissions, but it can open and edit Microsoft Office files that you can download from SharePoint.
Can WPS Office edit files downloaded from SharePoint?
Yes. WPS Office supports Microsoft Word, Excel, and PowerPoint formats, so you can open, edit, and save documents from SharePoint when you have download access.
