I installed the Directory plugin.
I created a few categories.
I added a listing.
I went to view the listing.
Under the list the following message appears:
Warning: Invalid argument supplied for foreach() in /wp-content/plugins/directory/ui-front/general/display-custom-fields-values.php on line 45
I have removed my hosting info from the error message.
I have now deactivated the plugin after deactivating and reactivating the plugin.
