[Plugin: Onswipe] Errors

This is displayed on every page in the admin and all over the place on the dashboard:
Notice: Undefined index: page in /…/wp-content/plugins/onswipe/themes/warp/init-options.php on line 4

This is on the options page:

Onswipe displays a beautiful app-like experience to visitors browsing with an iPad.

Notice: Undefined variable: is_disabled in /var/www/vhosts/wesleytodd.com/subdomains/dev/httpdocs/wp-content/plugins/onswipe/themes/warp/views/panels/options-panel.php on line 63
checked=’checked’> Display a special theme for iPad users

And it will not save the options when I make a change.
