 * Hi Lebasca
 * When I active the plugin, this message appears (debug mode ON) :
 * Strict Standards: call_user_func_array() expects parameter 1 to be a valid callback,
   non-static method ColumnPost_Widget::register_widget() should not be called statically
   in H:\xampp-portable\htdocs\precisadeajuda2\wp-includes\plugin.php on line 429
   
   I’m using wordpress 3.8 and PHP 5.4.7
 * Can you fix this?
 * Thank you in advance

 * Hi riderkick,
 * Try the following:
    1. Go to php.ini and change the following: error_reporting
   = E_ALL | E_STRICT to error_reporting = E_ALL & ~E_NOTICE display_errors = On
   to display_errors = Off 2. If the above still doesn’t help you, do the following:
   In the domains index.php file set it like inside the php division. ini_set(‘display_errors’,
   0); 3. If the step 1 or 2 doesn’t fix your problem, upgrade the version of your
   php. I am using PHP 5.5.6
 * Regards,
    Lebasca
