Unable to save wiki update

[mbbroberg (Matt Broberg)]

I made some edits to an existing wiki and I can no longer save it. I thought I might have added something odd, so I removed the update and it still won’t save. It is saving the update to drafts, so that’s nice at least.

Any ideas?

Can you please check the server logs at /logs for the 422 response?

[joffreyjaffeux]

Can you try in safe mode please ? How to use Discourse Safe Mode

If it works with safe-mode, please give me the list of your plugins/components/any custom theme you would have.

[joffreyjaffeux]

I’m quite sure this will solve your issue:

https://github.com/discourse/discourse/pull/9161

Will merge it once tests pass.

[codinghorror (Jeff Atwood)]

Does that need to be backported?

[joffreyjaffeux]

I’m unsure yet how this state is possible, it comes from when we added multi category hierarchy support.

Will try to have a repro tomorrow and see if it’s worth backporting.
