Solution: In this case the fastest way to solve the issue is by following this steps: - Create a full backup of the site. - Connect to the database -> in the wp_posts table delete the row with element ID = 7283 - Double check if the issue persists. - Repeat this process if the error message appears again with another ID.
Note: Please don't forget to create a full backup of the site because if something goes wrong you will have to restore it.
