Reply To: Slider revolution doesn't load modules

The problem is that i have a slider in the hope page, and I see it correctly in the frontend and in the WpBackery builder, it means that if I go to the browser of the slider in Slider Revolution I have to see this slider in the list of the slider, but the list is empty!
Do you see some sliders in the list??

I have enabled wp debug and i have these errors:
Notice: Trying to get property ‘version’ of non-object in /home/uppstep/www/riversan/wp-content/plugins/revslider/admin/includes/functions-admin.class.php on line 363

Notice: Trying to get property ‘code’ of non-object in /home/uppstep/www/riversan/wp-content/plugins/revslider/admin/includes/functions-admin.class.php on line 363

Another problem:
I tried to import manually another slider, but it doesn’t work.

Thank you
