Yes, I’ve been using this plugin for months and have ran into several problems with it. I purchased to PRO version, which is full of bugs, as you noticed..
Support is not great and the functionality is limited. If you can, try a different plugin.
In the listing_contact_form.php, you can set the subject of the email sent through the contact form.
Line 13:
$subject = “Listing #”.$ListingDetails->listing_id.” Inquiry (“.date(“m/d/y”).”)”;
You could attach your custom field in there, or even just use the listing ID as the reference number. Then you wouldn’t have any problem..?
Yes. I am having the same problem. The search is working, but when I select a custom field that has been created and selected as “searchable” (PRO version) it returns nothing, even though there are listings matching that custom field.
