Multisite Setup

Hi,

I try to set up WordPress Multisite and have completed all the steps except adding a code in. .htaccess. I can not find .htaccess at all?

I started writing with a person on live chat and was notified to give you access via the wordpress admin panel. The problem is that Wpmu dev has disappeared from the admin panel after I started setting up a multisite so I can not give you access (but I can send you the login to siteground and wordpress).

I also see that all the plugins are disabled at premium.wpmudev.org/hub/my-websites/ (including Wpmu dev)

We have used other platforms to create websites and online stores for customers, so wordpress is new to me.

Can you help us set up WordPress multisite?
