Resolution
The issue you’re seeing is likely a result of corrupted browser data. Please try the following troubleshooting steps to resolve the error and restore your access to the sites:
- Clear your browser's cache and cookies for all time
 - Open WorldShare/WorldCat Discovery in an incognito/private browser window
 - Open WorldShare/WorldCat Discovery in a browser you don't typically use
 - Open WorldShare/WorldCat Discovery using a clean link: 
    
- WorldShare: https://[REGISTRY-ID].share.worldcat.org/wms
 - WorldCat Discovery: https://[REGISTRY-ID].on.worldcat.org/discovery
        
- If you don't know your library's registry ID, you can look it up on the WorldCat Registry website.
 
 
 
If none of the troubleshooting steps above resolve the issue, have a colleague who can access WorldShare and has Admin roles review your account to confirm that an email address is listed in the Library Record section of the profile. If an email address is not listed, provide one, mark it as primary, and save the profile, then try to sign in again.
If you are library staff and these steps don't resolve the problem, contact OCLC Support. If you are a library patron, contact your library staff for assistance.
