How to enable inactive fields I have a content type with a field that has been set to inactive. This happened after I reverted my feature in an attempt to undo a change I made to the content type.

The error message given is the following:


  This content type has inactive fields. Inactive fields are not included in lists of available fields until their modules are enabled.


I've disabled and re-enabled the feature module, but the field is still inactive.

How can I activate my field?
I've had this quite a few times, I'm not sure what the initial problem is but I've solved it by doing either one of the following:


Disabling the feature and re-enabling it
If above fails disable delete content type then re-enable (not an option if there existing content on the site)
Manually editing the content_field_instance table (D6) and enabling it there.
