WordPress 3.0.4 – the Return of the Custom Field Bug
After upgrading to the latest stable WordPress version 3.0.4 I ran into an old issue I haven’t see for almost two years. Clicking “Publish” or “Save Draft” when writing a new post seems to remove some custom fields. If you re-add the custom field and click “Update”, the entry stays. But it goes away again once you use the “Save Draft” or “Publish”. Not yet sure what causes this, but the problem appears in multiple WordPress installations that don’t have much in common in terms of themes or plugins. For now my best advice is to avoid WP 3.0.4 until this problem has been resolved.
