og:description not pulling contents from meta

Question

I am recently experiencing problems with metadata for Facebook and I was wondering if any other EE user has experienced the same.

In principle, the code should be fine and was actually working till not long ago. At some point it stopped doing so and FB scraps no content for og:description (and neither for meta:description for that matter). I thought it might have been aproblem with my descriptions starting with the

tag so I installed streeng and did this:

<meta property="og:type" content="article">
<meta property="og:title" content="{pages_title}">
<meta property="og:description" {exp:streeng allowed="none"}content="{pages_summary}"{/exp:streeng}>
{if picture}
<meta property="og:image" content="{picture}">
{if:else}
<meta property="og:image" content="http://www.ecfr.eu/page/-/logoxfb.png?v=1415186136948">
<meta property="og:url" content="{url_title_path='article'}">

but still no result. All other meta works.. any idea?

Answer 1

I know this will sound silly but have you tried changing your quotation marks within the EE tag to single quotes. I run into this issue all the time even though it 'looks' like it shouldn't be an issue.

<meta property="og:description" {exp:streeng allowed='none'}content="{pages_summary}"{/exp:streeng}>

I always use single quotes ( ' ) within an EE tag since HTML uses double ones ( " ).

Facebook caches data so if you're testing a specific URL and not seeing the results as you'd expect, it's most likely their cache is storing incorrect information.

You can force clear the Facebook cache for a specific url using their Debugger tool.
