Hello leandro980,
I took a look at your site code and then looked into the issue. According to this post there are several things you may want to try with the Yoast plugin or NGFB plugin. They state a conflict with Yoast, though the user did remove the plugin completely. They discuss several points about the og: image meta entry. Try placing the image in a different location such as the root of your files. It shouldn’t make a difference, but make sure the file name is ALL lower case as the servers are generally case-sensitive (though your current link does work when I tried looking at it).
I was also checking on the image size. The preferred size is 1200 x 630 pixels. You can find more information on Open Graph here.
There are 3 good plugins that may help with this issue: NextGEN Facebook, Social Media Share Buttons, and WPSSO Social Sharing Buttons.
I hope that helps to resolve the problem!
Regards,
Arnel
Thank You arncus!
I’m trying now NGFB. As soon i’ll have a new articla i will try if the plugin works. In the thread you’ve published they say that once the link is shared the errors will remain (as soon FB will clear its own cache i suppose).
I’ll let you know.
Thanks again!
None of the solutions worked. It’s gettin very frustrating.
I’ve installed NGFB, deactivated Yoast etc. etc. But nothing, FB scraper doesn’t read the og tags!
