Cannot Create New Topics

Product Support

AI-generated summary

davidkingham reports that after updating, users can no longer create topics, receiving an error: Category not allowed for topic creation, despite having proper permissions. The issue persists in safe mode and affects specific categories—those under “Image Critiques”—while others work fine. Lilly asks if the issue is category-specific and notes users can draft topics but fail to post them. davidkingham observes the category dropdown in /new-topic only shows working categories, hinting at a deeper issue. Lilly suggests checking Full_Member group settings, but davidkingham rules this out, confirming permissions are identical and non-admin accounts can post in other categories. Eventually, davidkingham identifies the bug as originating from the Custom Wizard Plugin, working with Pavilion to fix it—despite occurring in safe mode, suggesting it bypasses standard safeguards. Lilly offers encouragement. pfaffman suggests checking if the discourse-category-lockdown plugin might be involved. The issue remains unresolved but is now being actively debugged.

After updating to latest yesterday my users cannot create topics anymore. They get the following error: An error occurred: You supplied invalid parameters to the request: Category not allowed for topic creation. Nothing has changed, they have permissions to the category. I am able to repro this in safe mode as well.

I see the following in the console:

Nothing relevant in the logs. Any ideas?

Is this happening in one category or all of them?

I saw the topic about it on your forum (I tried to join but no button lol). It seems users can create a topic in the editor but the create topic button fails when they post it. :thinking:

Okay, this is interesting. If I go straight to /new-topic the category dropdown only shows the categories they can successfully post in, even though the security settings are the same. Note all the categories in image critiques are missing.

hmmm :thinking: have you checked the Full_Member group settings?

I don’t think that’s it. One of the other categories that they can post in has the same settings, and I did verify that I can post in this category with a normal non-admin account. This is really bizarre.

I believe I’ve found the issue. It’s a bug in the Custom Wizard Plugin. I’m working with Pavilion to get this fixed. Strange that it still happened in safe mode, but it must go deeper than what safe mode can do. Thank you for your help Lilly.

I’m glad you may have located the issue and Pavilion is helping. Good Luck. :slight_smile:

Maybe make sure that GitHub - paviliondev/discourse-category-lockdown: Set all topics in a category to redirect, unless a member of specified groups · GitHub isn’t to blame.
