I have self-hosted Ghost instance and I’ve tried to upgrade it to the latest version yesterday.
During the upgrade process my connection dropped and dont think the update finished quite as expected. Now the blog is shown ok and the admin area is also shown ok but when I try to edit any page or post an error message is shown at the top:
Internal server error, cannot save page. unknown format "uri-reference" ignored in schema at path "#/properties/feature_image"
Anyone can help me with this?
