error settings not saved on multisite install

Hi,

I am testing your plugin on a multisite install.

But I see I am not able to save the settings on subsites. Main site is working.

Error displayed is:

SES_UNCAUGHT_EXCEPTION: TypeError: jQuery(…).offset() is undefined
wcusage_go_to_settings https://fr.oreca.network/wp-admin/admin.php?page=wcusage_settings&section=tab-pro-details:18865

Can you explain me this error ?

Regards.

Christophe D.
