Hi @DivyaSunkara
It looks like you either have too many websites created or excessive website bindings.
Try this.
In portal management
1. Under Website > Websites > Check if you have anything apart from the starter portal. If so you can delete the website.
or
1. Under Website > Website Bindings> Check if there is more than one entry. Delete the unwanted entry.
If none of the above options works. Then delete your portal and recreate it while creating "choose from existing website record". Trust me all your work will be there including custom scripting and custom layout.
Cheers
Hope it helps.
