Plugin preventing content from loading on single.php, users in 'all users' list

Here’s the output from my error_log:

[Tue Sep 24 03:42:21 2013] [error] [client 174.118.59.196] PHP Fatal error: Uncaught exception ‘Exception’ with message ‘Make sure you are passing in the correct parameters’ in wp-content/plugins/add-local-avatar/TwitterAPIExchange.php:45\nStack trace:\n#0 wp-content/plugins/add-local-avatar/avatars.php(173): TwitterAPIExchange->__construct(Array)\n#1 wp-content/plugins/add-local-avatar/avatars.php(1393): add_local_avatars->get_twitter_avatar(‘themightyberz’)\n#2 wp-content/plugins/add-local-avatar/avatars.php(819): get_avatar(125, ‘140’)\n#3 wp-content/plugins/add-local-avatar/avatars.php(790): add_local_avatars->avatar_uploader_table(Object(WP_User), ‘140’)\n#4 [internal function]: add_local_avatars->avatar_uploader_option(Object(WP_User))\n#5 wp-includes/plugin.php(406): call_user_func_array(Array, Array)\n#6 /var/www/vhosts/sala in wp-content/plugins/add-local-avatar/TwitterAPIExchange.php on line 45

Why are you throwing an exception on line 45? I had to comment this out in order to get my site working again..
