Hello Riccardo,
We have the regular updates on the theme and we had the last updates on past week. SuperMagPro is now VERSION: 1.2.3 and you are using the old version. I think, automatic updates is not activated on your theme. Please read this post and know how to setup for automatic updates. https://www.acmethemes.com/blog/2016/06/activate-theme-license-to-receive-automatic-updates/
After activating it, make sure you had all the changes through Child Theme. If you had edited codes on parent theme, all the changes will lost.
Regards
