@neki it seems for this particular template/theme the issue tracker is at https://github.com/giterlizzi/dokuwiki-template-bootstrap3/issues
@nebulon Thank you for your response. I checked database integrity in LS and deleted old surveys. After this operation, update run smoothly in Cloudron ... thank you!
@nebulon Hi Johannes,
I have just updated to the latest version of LS and it seems to be OK.
Thank you very much for your help. I have learnt how to use backups 🙂 and my takeaway is that it would be better to update manually (and backup first).
All the best,
@girish Hi, it said that login script could not be loaded. I thought that the problem would be uBlock so I disabled it and it works.
