Getting error in multisite

Hi Team,

I have been developing over page builder and integrating it in my themes since 2 years but never had this issue.

Everything is fine is single setup but when i do multiple setup i get this error
Fatal error: Cannot use object of type stdClass as array in /home/thmclub/public_html/themes/zeno/wp-content/plugins/so-widgets-bundle/base/siteorigin-widget.class.php on line 331

What might be causing this ? Any help would be appreciated.

Thanks
