dartiss on "[Plugin: WordPress] Can't edit post information"

Hi David,

Ok for the first one - editing a post:
- If I click on any of the edit links for Status, Visibility, Publish date, Publicise - either nothing happens or the page just seems to refresh without letting me change any of those.

- For Yoast SEO - in the post I can see the traffic light, settings and share icons, but no fields to enter anything and can't click on those.

- For Jetpack - if I click on Site States, or My Jetpack or any of the options, I just get the Jetpack header and footer with no other information.

- In posts when I add a featured image it goes through the process of adding but at saving stage it redirects to a blank page and if I click the back arrow I go back to a blank post. Sometimes if I just go out and back my post is saved as a draft with the featured image, but not always.

To be honest, I'm not sure what caused the change, if it was an update or plugin etc. I've tried uninstalling some plugins. I also then tried to uninstall and reinstall Yoast SEO, but then also got error messages when trying to add plugins again, but that came right and I was able to reinstall but still have the same issues.
