Error on install

Thanks for creating this plugin.

I got the following error upon installation:
Warning: Illegal string offset ‘slug_view’ in /home/…/public_html/…/wp-content/plugins/ultimate-member-wp-user-frontend-addon/actions.php on line 3 (also on line 4).

My set-up is WordPress 4.1.1, Ultimate Member 1.0.69 and WP User Frontend 1.3.2.
