Widgets not showing in side bar.

Hi,

GP Support suggested I raise a topic here

I have GP Premium.

Since yesterday the widgets are not showing in the sidebar. I contacted site support and they came back with the following:
There seems to be an internal issue and due to which it not showing the sidebar. You will have to contact your theme provider and ask them to look into it as that will certainly help.

You can check my site here.

Kindly guide me to what I can do to resolve this.
Thank you and have a nice day.

Best regards
Marisa
