I have a situation whereby a tag has been added to a post and saved. This tag has a spelling mistake, so I go back and edit it, but after saving it it reverts to the incorrect version.
Next I try deleting the tag from the post and saving, then adding a new correctly spelled tag. Still it reverts.
I even went into the database via phpmyadmin and removed the incorrect version and references to it from the tables ‘wp_terms’, ‘wp_term_relationships’, and ‘wp_term_taxonomy’. This was the only successful way of changing the tag to the one I want, but as soon as another edit it made to the post – any edit, not just on the tag – the tag reverts to the original one that is incorrect.
I’ve tried using the Advanced Tag Entry plugin but the tag still reverts to the wrong one after an edit.
Is this a bug or am I doing something incredibly stupid?
