Can you please send us some valid wp credentials in a private reply? So we can investigate why is this happening.
Theme does not have any issue. It is been tested with multi-site as well.
Note: support time is from Monday to Friday, 9AM to 5PM (UTC +1:00). We reply to questions according to their arrival time. The oldest first. So replying non-stop to your own ticket will only move it up in line and delay the time we can get to you. We are doing our best to reply to all of you asap. But during the waiting time, we kindly ask for your patience.
