Problems with website

I have both Jetpack and MPMU DEV on my website. –plus several more plugins that I have purchased through JVZOO. The day before yesterday something weird happened, and I lost the ability to share my posts to my social media sites. I built this website myself, but it was all guess work. I have no idea how to fix this. HELP.

Also, can I create two pages that I can post from on one website? I’d like a page for Books I’ve Reviewed and one specifically for blog posts.

I’m also haveing difficulty with setting up categories that work on my Glorias blog page
