trouble getting posts up after plugin update

I updated plugins on my website on Friday: the entire site disappeared and was replaced by a grey screen.
I resolved that issue by deactivating all the plugins and then re-activating one by one to see which one was causing the problem.
I wasn’t able to update “Black Studio TinyMCE Widget” (it doesn’t update) and when I reactivate “Dynamic Widgets” the entire website disappears again.

My site is back up and so is most of the content. But my posts are not showing up on the home page. They are all there in the editor but do not show up on my home page, nor can I find links to them under the different tabs.

Can someone help me get them all back up? Does it have something to do with those two plugins mentioned above?
