I have had a rough time getting the site set up... it seems like every time I try to change a theme or add a plugin I would find one that breaks it. I have learned to be selective and research.
Then I got everything working the way I needed it to. I'm so happy. The site went live today. Starting to get traffic. I found a problem with the way certain content was being delivered (streaming video). So I researched a bit and decided to install the JWVideo plugin.
Immediately after activating it any and all admin pages including adding posts or pages simply doesn't work on the root site or on the network admin. However, all the subsites admin still works, and the content on the root site still works.
So... this is not the same disaster I have been fighting all along... I feel like there may be some hope...
... is there any hope?
