Fatal error when activating plugin

Hi hi,

Love the plugin, but I noticed on one of the sites I use it on it has deactivated and I cannot reactivate it. Each time I try it throws a fatal error. I’ve tried updating the plugin, but it says the same thing.

The error is this:
Parse error: syntax error, unexpected '.', expecting ',' or ';' in /home/tobaccofactory/public_html/wp-content/plugins/insta-gallery/includes/controllers/FeedController.php on line 10

Any ideas why this might be happening?

Many thanks
