got an error installing plugin-in (1.3.1) on a site:
Fatal error: Cannot redeclare juiz_ltw_plugin_action_links() (previously declared in /var/www/margiedana/wp-content/plugins/juiz-last-tweet-widget/juiz-last-tweet.php:119) in /var/www/margiedana/wp-content/plugins/juiz-last-tweet-widget/juiz-last-tweet.php on line 119
Note sure how or why it happened because it's the only instance of the plugin on the server.
But anyways, turns out there's a space when you were checking if the function exists:
line 118: if ( !function_exists(' juiz_ltw_plugin_action_links')) {
Took the space out it works fine. Got your back brother!
