404 / Subsites not found WP Multi-Network

So, for the last days I’ve been battling the problem with the Multisite/Network error where the child-site is not working correctly. I’ve done multiple resets, going through a lot of forum threads and at this point most of the links are now purple. I’m new at back-end side of things, and though I find it quite interesting this personal project of mine has to be put online at some point, so as a last resort before jumping back to a simpler setup I’ll ask you guys.

I’ve tried different .htaccees and sunrise code and the last, updated ones, seems to be a step in the right direction (?). Before I could not access the Admin area for the the new Networks but I can do so at the moment; but posting is not working and the page itself is giving me no content.

I’m running it locally and have enabled the mod_rewrite and changed AllowOveride to All in the httpd.conf

Using the WP Multi Network plugin.

Thanks and have a good day!
