We run a website (desihiphop.com) on Wordpress that works very well with Facebook (usually). For the past couple of years (at least), Facebook was able to fetch every bit of Meta Data related to blog posts or articles or images from the site. And, at times when that failed, I just ran a quick Facebook Debugger on the link, and it would work again.
However, since last night, Facebook stopped fetching our meta data properly giving us the following error
Object at URL 'http://www.desihiphop.com/2015/02/ao-rayven-justice-keep-ridin/' of type 'website' is invalid because a required property 'og:title' of type 'string' was not provided.
It says that the og:title is not provided, but that's totally wrong!
I checked the source code, the og:title, and every other meta tags are there
I checked the SEO plugin on wordpress that we use - SEO Yoast - everything's perfect
I refreshed & updated all our plugins
I updated mysql & server software (just in case that had something to do with it)
I still don't know why facebook is not fetching that information for us... Any advice on this would be highly appreciated as we use social media to market our content heavily. It would help to have this solved as soon as possible, with your help.
