[solved] Strict Standards error

[korpirkor]

Yes, you should put it in every included php file. Better way will be use ini_set('error_reporting', ...);
You can configure this via .htaccess file too.  More info You w will find there: http://es.php.net/error_reporting

I said that, ini_set and htaccess were be better, because you have to type them only in ex. config.php or fileloc.php...
