As I was remebered to the issue through this thread I looked at the Opera-site and tried version 9.50Beta. And it works! At least here at my Linux box. Give it a try.

I'm, having exactly the same problem. Some profile, game pages, and chartz also fail to load.

 I did give it a try. Right before or right after posting originally, but on my linux machine, it still has the problem, but if yours is working and mine isn't, perhaps we could pinpoint a difference and narrow down where the issue is?

I'm not very experienced with linux things yet and I'm also not a programmer, but I opened Opera through Terminal to see if any errors pop up, and I got this when a page not working on vgchartz came up,

(operapluginwrapper:16626): Gtk-CRITICAL **: gtk_widget_destroy: assertion `GTK_IS_WIDGET (widget)' failed
The program 'operapluginwrapper' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 38855 error_code 3 request_code 2 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
opera: Plug-in 16626 is not responding. It will be closed.
opera: Define environment variable OPERA_KEEP_BLOCKED_PLUGIN to keep blocked plug-ins.
 

I dunno yet if this is just a problem with my machine though or even related. I'll try to look into it some more later.
