Hello,
Point is that solution that we provided helped other clients. If that does not work for you then we need access to your site (WP Dashboard and FTP) to test and find out why that code fix does not work for you and find the other solution that would help.
So, please, provide us with the necessary access. Or create a staging site (full copy of the production site) and provide us with access to staging to allow us to test and help you.
Regards
