plugin doesn’t work anymore

Since the plugin update, it doesn’t work anymore.
There are several errors including the access to the https://villatheme.com/notices.php page.
As a result, all my page doesn’t work, this is due to the plugin since when I disable the LookBook plugin my page works again.
Moreover, it is impossible to go back to previous versions of the plugin.
What solutions do you have?
