 * Hey guys
 * I’m working on a website, where I’m trying to combine it with an event plugin
   and on the description this one sounds like the best for me.
 * I downloaded it and tried to set it up, but after the activation I got 2 errors:
 *     ```
       Strict Standards: Only variables should be assigned by reference in D:\xampp\htdocs\wordpress\wp-content\plugins\events-planner\system\epl-base.php on line 57
   
       Fatal error: Call-time pass-by-reference has been removed in D:\xampp\htdocs\wordpress\wp-content\plugins\events-planner\system\epl-util.php on line 1145
       ```
   
 * I have looked on the code (on these to lines) and can’t find any errors at all.
 * The first error code:
 *     ```
       if ( count( $libraries ) > 0 ) {
   
                   foreach ( $libraries as $library ) {
   
                       $lib = strtolower( str_replace( "-", "_", $library ) );
                       $this->$lib =& $this->load_library( $library );
                   }
               }
       ```
   
 * The second one:
 *     ```
       function clean_input( $data ) {
               return array_map( array( get_class(), 'clean_input_process' ), &$data );
           }
       ```
   
 * I’m using WordPress 3.5

 * Hi Karred.
 * Looks like you are running PHP 5.4!? I have fixed these in the Pro and will address
   them in the lite version soon.
 * Thanks, Abel

 * Karred, sorry, did not mention how to fix the issues. Please remove the & symbol
   from those lines and you will be good. There may be some other places that the
   error may pop up. In all cases, there will be the & symbol.
 * Thanks, Abel
