Error caused after activating the plugin

Please upgrade to version 1.2

It still does it even in version 1.2

This widget is meant to work with our Jobify theme. To avoid this error if you aren’t using the theme, replace widgets.php with this: https://gist.github.com/spencerfinnell/6104752/raw/df981ee2882d18df56f1466fe43f590ede5ca267/gistfile1.php

Thanks for the quick fix.
