 * Hi i updated the plugin, i noticed that some of the custom fields i had added
   does not show in the listing form, i went to edit the Unique meta key and saved
   the changes and this message appeared:
 * Your site seems to be slightly misconfigured.
 * Carbon Fields library encountered errors that may prevent your custom fields 
   or theme options to work properly. Here’s a quick summary of the issue:
 * 1. Unknown field type “listing-category”.
 * You might want to get in touch with a developer regarding the issue. If you feel
   adventurous, try enabling WP_DEBUG in your wp-config.php
 * can you help me out?
    thanks

 * Hi [@alexalp](https://wordpress.org/support/users/alexalp/)
 * Thanks for reporting the issue. Long story short, you have high likely created
   a field that you shouldn’t have been able to create. This happend because some
   validation rules within the fields editor failed to trigger due to the newest
   update to the carbon fields library broke the old validation system.
 * If you still have access to your website, the quickest way to to fix the issue
   is to wipe all your custom fields by going in Tools -> Posterno tools -> database
   and wipe all fields from there. Wait until the process has finished and it will
   restore fields back to default.
 * Once it’s restored back to default, you don’t need to create a “listing category”
   field. Posterno internally already handles that.
 * Remember you shouldn’t create the following fields:
 * – Listing category selector
    – Social profiles selector – Listing tags selector–
   Opening hours
 * I’ll be releasing a fix on Monday

 * The update has just been released. The list of fields types that cannot be used
   outside of the default fields are these:
 * – Listing category selector
    – Social profiles selector – Listing tags selector–

 * At the moment you can only hide fields from the frontend forms by marking them
   as “admin-only” – see here [https://docs.posterno.com/article/504-listings-custom-fields#t3](https://docs.posterno.com/article/504-listings-custom-fields#t3)
 * There currently is no plan to allow removal of the default fields from the admin
   panel ( listings post type page ). If more people request to remove the default
   fields from the post type page, I’d most definitely add an option to hide them
   but they’ll still be visible within the fields editor in the admin panel so they
   can be toggled.
