SEO, Opengraph, Metadata not being read in wordpress

General information for the website: Comics
Kind of development: Customization of existing website
Description of requirements/features: I have the yeost SEO wordpress plugin on my site. A child could use it and I have filled in the correct details. However, no SEO, no opengraph and no metadata is being read by google or by websites. For the opengraph the thumbnail I set within wordpress is not being displayed. For metadata and seo it is not being read by google even after two weeks.

No problem. I set the menu pages to be ignored in the robots.txt and they are still showing in google.

I have a customised theme and not sure if that is the problem.

Thanks
