My website is in the testing phase.
I installed a simple site.
For safety I have applied several tips, including've moved and renamed the wp-content folder.
Done this now my site is safer.
You can see it in http://webclientes.es.mialias.net
Now I try to make it multisite. I've changed the wp-config by adding the code [define ('WP_ALLOW_MULTISITE', true);] and also the htaccess
Now I have available in the tools menu "Network Configuration" option, but the option is not activated in the menu to manage the web sites.
Please see the attached image.
I await your advice.
Thank you very much.
