1) Share steps on how can I check and see the issue.
2) Please make a full backup of your site (files and database) and confirm it in your next reply.
If possible please provide access to the staging website, not production.
Please note, that I might need to do some debugging procedures like enable/disable plugins, switch themes, change the default language of the user account, and/or access your website database to debug the issue furtherly.
I will share with you any changes or steps done in this process. Please let me know if you do not agree with the above or if I do not have your permission for any.
I would need to access both your site's wp-admin and FTP account, if possible.
I have enabled the private username and password fields in your next reply.
I suggest you create a new user, set it as an administrator and then add those credentials in the private fields mentioned.
You can safely add your information into these fields.
3) In order to expedite handling your support requests, can you please share WPML support debug information from your site.
