"service unavailable"

Hello, as soon as I want to add a photo to a product, I get an error message that the service is unavailable. What is the reason for this?
Best regards, Lisa

Search the table “cscart_images_links” “detailed_id” field for 2 instances of 16777215. I’m not sure how that would happen but you probably need to delete one of them.

This value is maximum value for the column with the MEDIUMINT type.

@kauftregional it is required to change column type from MEDIUMINT(8) to INT(11)

The same changes may be required for the cscart_images_links table
