Whew! I’m glad it’s been done!
Well originally, we couldn’t link up the 2 sites under one wordpress install, which, I did end up figuring out a while after posting this. We were experiencing 404’s and a few 403’s, but I was able to get that resolved doing a fresh install and mapping prior to doing anything else. That solved like 90% of my issues. On top of that I wasn’t able to see the customization preview or use the theme I wanted because it populated onto the main domain and not the sub. Also got that fixed, which has been amazing.
Now just having issues with Buddypress install and how to configure it with multisite. What we’d essentially like to do is have everyone who signs up on site A automatically gets an account on site B, and/or vice versa (however site A to site B works just fine), and figuring out how to configure Buddypress as primary on site A, but have the main forum on site B with the groups and everything. Currently getting 404 errors on all sites created with Buddypress.
