Can't deltete custom fields

[stefan@…]

Hi!

I'm getting tracError when trying to delete a custom field. It's sais I need to upgrade and then it works again but the customfields i'm trying to remove is still there.

It would be quite useful to get the actual error. Also, I'd like to know versions of Trac and your installed plugins. I strongly suspect this is a custom field provided/created by a plugin, and that plugin will complain and ask you to upgrade whenever you delete the field that it created. I know some hour/timing/estimation plugins do this to maintain needed custom fields. Try to disable plugins to find which one "hangs on" to the field(s) you want to remove.

This is no doubt because fields are removed other plugins depend on, and they will then require upgrade to resolve the issue - and thereby adding the fields again.

What they should do is provide their default settings using Option instead, and since [6485] CustomFieldAdminPlugin will not be able to delete such fields.
