Cannot delete a space

I cannot remove a global space or a personal space.

You can choose the option to remove the space, but the space is not actually deleted. I can go to the "Browse Pages" view and add a page to the space.

I reproduced the error in Confluence 4.3. A customer has reported this issue in a comment on the Confluence documentation, so it probably applies to other versions of Confluence too.

List of plugins known to cause this issue:

• Confluence Bubbles Plugin (Adaptavist)
• Descendant Notifications Plugin (Adaptavist)

Workaround/Steps to resolve once a space has been semi-deleted

1. Upgrade to Confluence 4.3.1 or above
2. If you cannot upgrade to Confluence 4.3.1, disable these plugins if they are installed:
   • Confluence Bubbles Plugin (Adaptavist)
   • Descendant Notifications Plugin (Adaptavist)
3. Go to <your-Confluence-url>/spaces/editspace.action?key=~username
4. Click on Remove Space to remove the space entirely
5. Recreate the space
6. Re-enable the plugins if you had to disable them in Step 2
