Hi when I tried to activate the plugin I get the error below:

Fatal error: Cannot redeclare run_simple_live_editor() (previously declared in /home/axisleba/public_html/test/wp-content/plugins/simple-live-editor/simple-live-editor.php:79) in /home/axisleba/public_html/test/wp-content/plugins/simple-live-editor-master/simple-live-editor.php on line 79

which's $plugin = new Simple_Live_Editor();
