Yoast SEO not showing any information at all

When I click SEO I see all of the tabs – General, Company Info, Webmaster Tools, Security, OnPage.org – but when I click on them nothing appears. I’m wondering if I’ve installed another plugin that’s affecting it. I’ve tried deactivating a few but it hasn’t made any difference.

The plugins I have activated are:

Beaver Builder
Contact Form 7
Custom Headers and Footers
Easy Google Fonts
Easy Pricing Tables Lite by Fatcat Apps
Google Analyticator
PopupAlly
Responsive WordPress Slider – Soliloquy Lite
RRF Scroll To Top
Shareaholic | share buttons, analytics, related content
Simple Backup
Simple Custom CSS
WP Super Cache
Yoast SEO

The ones I’ve disabled are:

All In One WP Security
Jetpack by WordPress.com
Theme Authenticity Checker (TAC)

These are the most recent plugins I’ve installed so I was hoping it might have been one of them but, as I said, it hasn’t made any difference.

Does anyone know what might affect the Yoast SEO plugin please?

Also, I no longer have snippet editor or content analysis on my pages.

I’m not sure if it’s related but when I share my site with Facebook it now shows (no title) and I see 2 lines of text the same.
