issue with thumbnail image for sharing site on social media

Hi there!

I use AIO Seo (free version) and been having problems with the image appearing when I share on social media.

After being advised here to contact my hosting provider (Littleoak.net), I did this. And the problem is now HALF-RESOLVED.

I am still having the following issues. If you could help or direct me on what to do, that would be great!

1. When sharing the URL links, the images not do appear as I have configured on AIOS SEO plugin. BUT, strangely the metadata does NOT appear. Only the page title/tagline.
2. Shown on the facebook debugger and also when I try to share any URL links prefix that is not the “https”, the URLs do not work and have an error. That is: if I use “http” or just “www”. This is a bit of a problem as if someone else shares my website, they would unlikely put https, but rather would just use the “www”.

The 2 main pages I am particularly concerned with are my homepage and /elderheal.

Are these 2 issues still related to my hosting provider? Or is this AIO SEO issue?

Please let me know now to proceed.

Thanks heaps!
