Safari 5.1 on OS Lion

[Wing]

I have upgraded my iMac from SL to Lion, however, now I have a problem browsing the web with Safari 5.1, some contents could not be displayed, they displayed as blank. How can I solve this problem?

..., some contents could not be displayed, they displayed as blank. ...

Which content? Just in case you don't have it installed, download and install the Flash plug-in.

some pictures couldn't be displayed, where I can download the flash plug-in?

however, I can view youtube videos, I am guessing I have the flash player installed...

YouTube uses HTML5 on occasion, so no, you most likely DO NOT have the flash plugin.

Get it from there, and give it a try!

I have installed the flash plug-in, but still experiencing the same problem.

You should completely clear Safari history/cache, essentially reset it. Try it then.

tried resetting the Safari, reinstalled the flash player. But the problem is still there

Try a different browser to test. Either Firefox or Chrome, make sure NOT to import any settings, however.

It appears as though you may have security setting that blocks [images from] cross-site links. Check your firewall settings.

Where I can change the settings?
When I am using Chrome, everything is ok...
