Hi Katrin.
I didn't see any pages, can you point me to them if they still need to be deleted?
The ones I noticed were for the 4 May 2023 on the recent changes page, for example: https://wiki.koha-community.org/wiki/White_Label_SEO_Audits
It looks like this form might be to blame:
It looks like we only want:
https://wiki.koha-community.org/wiki/Special:RequestAccount
I am not sure what needs to be changed in configuration to go back to have only moderated account creation, but it seems these kinds of settings have to be changed server side. Maybe we are using this? https://www.mediawiki.org/wiki/Extension:ConfirmAccount
I'll add a comment on bug 23073 - hopefully Thomas can have a look at the configuration: https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23073 David
