I have problem with Advanced Custom Fields plugin in my Wordpress site. When I tried to add the 15th field WP redirects me to posts instead of saving the field. It's server issue beacuse I've cloned the WP with database to another server and it works fine.
I've found this tutorial but on mentioned server they haven't got the
PHP suhosin support, and they don't know how to solve this.
Do anybody knows any workaround to solve this issue ? I've tried both php.ini and .htaccess methods.
