Sorry to hear that, it sounds like you will need to restore your forum from backup
In my nodebb installation the summary mails contain links that do not exist.
They include this link: https://forum.church.tools/topic
But this leads to an error page.
Is there a way to configue the summary mail, or is there something else that is wrong in my installation?
I think this was fixed here https://github.com/NodeBB/NodeBB/issues/9382. It will be included in 1.17.0
thanks for the fast answer
