 * When I download and activate the plugin, I get the orange error notifications
   that say
 * > “Notice: Undefined index: which in /vagrant/wordpress/wp-content/plugins/awesome-
   > filterable-portfolio/afp.php on line 814”.
 *  They point to lines 814, 833, 856, 864, and 874. This blotches out my entire
   sidebar so I have to deactivate the plugin in order to navigate my dashboard.
 * Another error is stated above my list of plugins that says,
 * > “The plugin generated 8505 characters of unexpected output during activation.
   > If you notice “headers already sent” messages, problems with syndication feeds
   > or other issues, try deactivating or removing this plugin.”
 * I’ve tried switching to the twentyfifteen theme, but I still get the errors, 
   and I’ve tried installing the plugin on two different unrelated computers on 
   two unrelated local staging sites with different themes. I’ve also tried removing
   all of my other plugins in case there was a conflict, but to no avail.
 * I don’t suppose this is a browser problem? In both cases I’ve used firefox. That
   aside, I’m at a loss as to what’s causing these errors.
