I'm free to work immediately
Hi there,
It can be something in server side php code. I will have to check the plugin. You will need to provide ftp access and wp-admin access to check and verify functionality.
I am available and I can start this project now. 15 Eur for one hour and I hope, it will be get fix in this time, if there isn't any bigger issue.
Please initiate chat for further discussion.
Thanks,
Best Regards,
