Multi Site Install Instructions

Hi

I have a multisite. I have it activated on a few blogs (for example https://capeholidays.info).
I checked this site https://capeholidays.info manually and the dates stayed the same.

My Hostgator host came back saying you

have no caching implemented

.

I now want to check the installation and I now decided to also activate it on the route or main blog.

My first issue is that the main site’s .htaccess file needs to be updated. Should I do this and then for every other blog as well?
