Facebook and Meta tags - Joomla! Forum - community, help and support

hi!
i have following doubt, hope proper place

when try share in facebook link points website homepage (www.mysite.com), facebook loading "loreipsum i" title,some "loreipsumblahblah" description , "big_white.png" default logo.

i went articles manager, , in article assigned home menu item, called "lore ipsum i", modified title ("newtitle"), added metadata description(as blank),some metakeys, , changed "intro image" , "full intro image" in images/links section. chrome orb should appear.

i saved article, tried again in facebook content still wrong.

then went global configuration->site , added there "metadata description" too. facebook still loads(my fault,for sure) incorrectly title,description , content of home page.

then discovered called open graph, installed plugin create og metatags "loreipsum i" article, facebook loves them(accordingly web), still nothing.

oddly enough sourcecode of home webpage has tons of metatags:

code: select all

<meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <meta name="keywords" content="tag1,tag2,tag3" />
  <meta name="author" content="super user" />
  <meta property="og:title" content="thistitle" />
  <meta property="og:type" content="article" />
  <meta property="og:url" content="http://www.mysite.com/" />
  <meta property="og:image" content="http://www.mysite.com/images/google-chrome-logo1.png" />
  <meta property="og:site_name" content="http://www.mysite.com" />
  <meta property="og:description" content="my site wants nice site everyone" />
  <meta name="description" content="my site wants nice site everyone" />
  <meta name="generator" content="joomla! - open source content management" />

i sure missing something.may point me proper rtfm or me finding issue?
thanks lot!

i answer myself after knocking head against wall.
seems facebook has cache too. if had created correctly metatags, has stored old info.
there little trick force facebook cache again info site:
https://developers.facebook.com/tools/debug
add link there, hit go, , voila, cache deleted , new info added.otherwise have wait till facebook decides update cache(24 hours or so)
