Try using https on the linked image, otherwise you are trying to serve an insecure resource on a secure link. Does not matter here since the site is http only.
Already tried, doesn't matter, sorry. Any other ideas? :)
temporarily disable fancybox and see if that does it. (as well as put it back to https or it will not serve)
http://www.elkarte.it/community/index.php?topic=108.msg341#msg341 <= looks good on a more or less borked install, likely an issue with an addon...
I uninstalled Fancybox and now it works. Good instincts!
So, what do I do in order to keep the add on too?
Enable the "Don't attach fancybox to linked BBC images" in the addon settings
That will, or should, prevent it from interfering with that image. It will however also disable it from working on photo share links i.e. imageshack etc.
Thanks! Worked like a charm. :)
