Multi-site issue

Hi Supsystic,

I’ve got an issue with Photo Gallery by Supsystic plugin installed for multi-site.

The scenario:
1. Choose one of multi-site on admin page.
2. Press “new gallery”.
3. Put some gallery name and press Save button.
A gallery doesn’t creating and page redirecting to /undefined URL.

I’d checked the AJAX request/response and I’d seen:
wp.ajax.settings.url – https://www.domain.com/sitename/wp-admin/admin-ajax.php
response.url – undefined

As result the page had redirected to URL: https://www.domain.com/sitename/wp-admin/undefined

The gallery management works OK for main site of network but, unfortunately, not works for one of multi-site.

I will be very happy if you help me solve this issue.

Thanks.
