Now it stops working. I get the title of the page instead of the custom post type. The: "get_the_title($_POST['_wpcf_belongs_CPT_id']) " stops working.
What has to be the new way to get thew title of the parent.
If is possible I don't want to migrate to the new relationships. This is the only place were I use relationships.
In addition to the above, could you please share problem URL where you added your form with access details?
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).
I have set the next reply to private which means only you and I have access to it.
