I committed a fix for the null column .. the official repo is GitHub - discourse/discourse-signatures: A Discourse Plugin to show user signatures below posts · GitHub be sure to update your app.yml.

[image] barreeeiroo: /var/www/discourse/plugins/discourse-signatures/plugin.rb:41:in `block (2 levels) in activate!’ It looks like a problem with the discourse-signatures plugin.

Someone is trying to cook a post with raw == nil … that is not supported.

I’ll try again disabling the plugin

Disabling the plugin doesn’t fix the problem

[image] sam: trying to cook a post with raw == nil So basically you have a null post (no body, no content) on your site, in your database.. we don’t support that.

But that’s not possible :confused: Can I modify the backup and try to find that null post?

Allright Tomorrow I will rebuild the site without the plugin signatures and see what happens

Yes, without signatures plugin the backup can be restored Could you fix the plugin? :pray:
