It looks like there are just no fields in the form which is causing this warning. * Thread Starter [ThinkByDesign](https://wordpress.org/support/users/thinkbydesign/) * (@thinkbydesign) * [9 years, 3 months ago](https://wordpress.org/support/topic/invalid-2/#post-8844579) * No code that I’ve added. It would have to have come from a plugin, configuration, etc. * Thread Starter [ThinkByDesign](https://wordpress.org/support/users/thinkbydesign/) * (@thinkbydesign) * [9 years, 3 months ago](https://wordpress.org/support/topic/invalid-2/#post-8844587) * I should clarify. I’ve not added or modified any of the code – only installed and configured the plugins. * Thread Starter [ThinkByDesign](https://wordpress.org/support/users/thinkbydesign/) * (@thinkbydesign) * [9 years, 3 months ago](https://wordpress.org/support/topic/invalid-2/#post-8844834) * I tried disabling all plugins except the one that forces SSL and those for wpadverts, but no change. I tried creating a listing through the admin side interface, and was able to do that, but when I tried to view it I get invalid foreach argument errors in wpadverts-custom-fields.php (see [https://dev.dailyadsonline.com/advert/test/](https://dev.dailyadsonline.com/advert/test/)– ignore the ssl complaints.) * Plugin Author [Greg Winiarski](https://wordpress.org/support/users/gwin/) * (@gwin) * [9 years, 3 months ago](https://wordpress.org/support/topic/invalid-2/#post-8846738) * Hmm i am not really sure to be honest, it just looks like the [adverts_add] form does not have any fields for some reason. * Can you add in wpadverts-mal.php file before * ``` foreach($form["field"] as $i => $field) { ``` * line * ``` echo "
";
       print_r($form);
       echo "
"; ``` * refresh the page, then copy and paste the result here, or even better send them to me via contact form here [https://wpadverts.com/contact/](https://wpadverts.com/contact/) in case the form has some private data. * Thread Starter [ThinkByDesign](https://wordpress.org/support/users/thinkbydesign/) * (@thinkbydesign) * [9 years, 3 months ago](https://wordpress.org/support/topic/invalid-2/#post-8846853) * Array ( [name] => advert [action] => [field] => [form_scheme_id] => 129 ) * Thread Starter [ThinkByDesign](https://wordpress.org/support/users/thinkbydesign/) * (@thinkbydesign) * [9 years, 3 months ago](https://wordpress.org/support/topic/invalid-2/#post-8850252) * I’ve sent a few messages through your contact form, but haven’t seen any replies from you by email.

It is being caused by Custom Fields add- on if you have custom form created for the [adverts_add] form, but the custom form was never edited (so basically the scheme is blank). * The solution is to either stop using this particular custom form or edit the form from wp-admin / Classifieds / Options / Custom Fields panel and click the“ Update” button without changing anything so some form structure will be applied to the form. * Thread Starter [ThinkByDesign](https://wordpress.org/support/users/thinkbydesign/) * (@thinkbydesign) * [9 years, 3 months ago](https://wordpress.org/support/topic/invalid-2/#post-8853796) * Yep.
