Wiki does not have any revision to revert

[cmdntd]

I see on button of a wiki message there are 20 edits. But when go to revert, there is not any revision.
So I do not know if wiki for message could have a error. Could you check this, please?

We will need more help here to produce and fix this bug. Can you help us by sharing …

• Do you see any error message in your browser console? (all good if you can’t get this)
• Can you click on raw and see if you have any results?
• If you’re admin you can check staff action logs /admin/logs/staff_action_logs and look for post_edits to see what may have caused this
• Anything else you think can be useful for us to reproduce the bug
