I have recently upgraded a website to Joomla 3.3.6 with Purity III template, but now when a user shares an article link to Facebook non of the info such as title, image, description and etc. is shown.
I've tested the links with the Facebook debugger and read some possible solutions on the net but it looks like I can't find a way out
I've tryied with GZip on and off and nothing changed. I tried with SEF urls and no progress there ether. Then I read that I have to define the open graph meta tags explicitly, but not sure in which .php file should I do this. Any ideas?
