Hi Niyas,

Thank you for your reply. And yes. You are right. When we add an slide into a channel, the channel uses the slide as a cover. In this case, the slide is embed in the Public Channel, and shows at slide's statistics "Embeds: mydomain.com" "2".

Also, I tried before, adding a new slide will let us delete the first one. And channel will renew its cover image. In other words, after starting a channel will always have one slide in it. Odoo will not let delete the last one.

But what if I need to reset all channels, deleting all slides? Is it possible?

Hi,

This slide you are trying to delete might be referenced in some other records of another model. So you have to remove the reference form there first and then delete this slide.

Just create a new slide and delete it, hope here the slide will get deleted without any issue, that confirms the issue is the above

Thanks
