suddenly I have started to get this exclamation mark icon in my blog.
Instead of displaying a slideshare embedded presentation (and sometimes it happens with the embedded youtube and vimeo videos as well):
At first I thought it was a php update problem, then I upgraded to WP version 3.2.1, than I disabled all unnecessary plugins. Oddly enough, now it's solved when viewing in it in google chrome, but it still sometimes doesn't work in firefox and it never shows correctly in safari.
(and it's not an issue of the theme, because, I've tryed it with the default "Kirby 0.3.2" theme as well)
Does anybody has any idea why this can be happening?
Thanks for the help.
