Hello. Thank you for contacting the Toolset support.
I would like to know how exactly you are trying to apply the filter and in addition to that I will also require to know your current setup.
*** 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 have set the next reply to private which means only you and I have access to it.
