All newsprogk5 modules display errors on frontend

Please help me out.
I'm on my localhost. And after setting up all my ngk5 modules like the tabgk5, all stories module, most commented module, and latest newsmodule, using ngk5 the all showed up but the following errors came up in all showing above each modules in the front end:

Notice: undefined variable: item in c:\xampp\work\modules\mod_news_pro_gk5\tmpl\view.php on line 341
Notice: undefined variable: img_output in c:\xampp\work\modules\mod_news_pro_gk5\tmpl\view.php on line 344

Please what's the solution?

This is not an error but notice and can be turned off in Joomla configuration:

OK thanks very much. It worked out fine...
but hope if I take my site to to host online from the local host, there won't be any repetition of same problem or consequences to solved problems?

No, it shouldn't.
