I just re-scraped your page
www.oapschat.co.uk/ on the Facebook Open Graph Debugger. The errors encountered indicate that the og:type is invalid only because there is an invalid og:image tag on the page.
You have the following tags on the page, but if you navigate to the URL for this og:image, you will get a 404 error
<meta property="og:image" content="http:/www.oapschat.co.uk/public_html/images/logo_big.jpg">
<meta property="og:image:type" content="image/jpeg">
<meta property="og:image:width" content="1200">
<meta property="og:image:height" content="1080">
These are not in the block of Open Graph tags that JFBConnect adds to the page, so you will need to figure out how they are getting added or what other extension is doing it. [Edited to add: If you've manually included the tag, I think you should just strip out the public_html from the URL so that it is
www.oapschat.co.uk/images/logo_big.jpg - this will bring you to a valid logo]
Please note that after you fix the og:image tag on the page, you will need to re-scrape the page by either going to our site socialdebug.com which forces a new scrape or to the Facebook Open Graph Debugger at
developers.facebook.com/tools/debug/ and then hitting 'Debug' then 'Fetch new scrape information'
