Sometimes it may be necessary to revoke your existing eBay token before re-activating it on StreetPricer.
This is usually when it has not expired on eBay, which means it still exists, and attempting to re-activate it here fails.
Since the token is issued by eBay, revoking it can only be done on eBay
In eBay, login in to your account.
Go to My eBay > Account > Site Preferences > Third Party Authorizations
Check if the token authorizing StreetPricer exists.
If it does.
