 * When I try to activate the plugin I get the following error:
 * Fatal error: Cannot redeclare class WP_Widget_Black_Studio_TinyMCE in /home6/
   injuryl8/public_html/wp-content/plugins/black-studio-tinymce-widget/black-studio-
   tinymce-widget.php on line 97
 * Guessing, I deactivated all other plugins but that didn’t work. Any thoughts 
   on what I need to do? Thanks

 * It looks like you have two instances of the plugin installed, or custom code 
   which embeds the plugin’s code.
    Please could you check if the plugin is listed
   twice in your plugin list? Also check via ftp the wp-content/plugins folder for
   duplicates. Which theme and which other plugins are you using?
