Can't create Wiki (as admin)

Support
1

Our Discourse instance displays a 403 error with the message: “You are not permitted to view the requested resource” when attempting to edit a post as Wiki.

What could be causing this issue? There is no related information in /logs.

2

Could you watch the browser console logs, and see if anything odd pops up there?

Of course, as I said I get → 403 “You are not permitted to view the requested resource”

Just to be sure, now the admin settings are group-allowed could you give them a once over to make sure admin and mod are default included for editing wikis (and maybe others if you have tags or images in there)

I mean like anything besides the 403, is anything else erroring?

Both added, for sure. Thanks for your reply.

I understand but there is nothing more (!)

I’m having trouble making a wiki post as well. I’m getting this error when trying to make one of my own posts a wiki, as well as trying to make another user’s post a wiki.

  • I’m an admin
  • Edit wiki post allowed groups is set to admins, moderators, everyone
  • Self wiki allowed groups is set to admins, moderators, everyone
  • Edit post allowed groups is set to admins, moderators, tl0
  • Edit all post groups is set to admins, moderators, tl4
  • The category’s security settings are set to allow everyone to see, reply, and create
  • The category does not have Make new topics wikis by default enabled - nor should it be, not every post should be a wiki in this category
  • The category does not have any category moderators
  • I tried to change post ownership to myself and make the post a wiki - did not work
  • I logged in as a test user with tl3 and created a post - did not work
  • I tried impersonating the user who made the post, to try and make it a wiki - did not work
  • I tried creating my own post and making it a wiki - did not work
  • I tried running the site in safe mode - did not work

I’m kind of out of ideas now, not sure what else to try!

Do you use any unofficial plugins?

Yes:

  • BBcode tabs
  • Discourse Category Restrictor
  • Custom Wizard
  • Dynamic Groups
  • Landing Pages
  • Private Replies
  • Private Topics

I went through and disabled each of these one by one and tested each time - still no luck. I disabled all of them, still no luck. I also tried running the site in safe mode, and it didn’t work either.

edited to add: I also just updated the site to v2026.01.0-latest and still no luck.

Hi Jen - are there any errors showing up in the console when you get the error message in the UI?

I’ve tried to replicate your settings on one of my self-hosted instances, but I cannot reproduce the issue and I can create and edit wiki posts as expected.

Yes - here’s what I’ve got in the console. Before I updated to v2026.01, there weren’t any references to video-thumbnail or video-placeholder. There aren’t any videos at all anywhere on this dev instance.

Here’s the console:

edited to add: I created a new category and enabled Make new topics wikis by default. I was able to make a new topic in this category which was a wiki. However, I get the same error as before when i click on Remove Wiki for that post.
