Hey the solution was posted by michiko and it works:
i solved the problem by changing the path from:
// File was executed in admin or plugin
require_once(‘exhibitimg/exhibit10i.php’);
require_once(‘exhibitimg/exhibit10p.php’);
to:
require_once(‘/home/www/htdocs/mysite.com/diary/wp-content/plugins/exhibitimg/exhibit10i.php’);
require_once(‘/home/www/htdocs/mysite.com/diary/wp-content/plugins/exhibitimg/exhibit10p.php’);
