Joomla! Template Entertainer PT - Item Support

hello is the slider integrated in the template?
is the audio player with the template?

Greetings dirk
Hello I have bought the Template Entertainer PT.
Then install the latest Joomla version and then the template.
If I want to activate the template now in the admin area the error message

0 Call to a member function get() on null
ALso I did it so far.
However, I get the admin menu shows that the unite-slider needs an update.
This I can not do on the page because he says the update link would be wrong ... If the unite-slider but not up-to-date he poses a security problem! What can I do ?
Hello we have now included under the main menu but unfortunately this is not visible on the phone .... what can we do that this is also visible on the phone?

Many Thanks
