Today I had a client call to tell me that they could not get to our "upload files" page. That they just got an error and after acknowledging that error were then presented with IE's default page could not be loaded "page".
After some digging, this client is using IE7 (possibly IE8) on Vista. I have one Vista machine in the shop, so I was able to duplicate this error (why do people use IE!!!!!).
Screenshots:
This one is from IE7/XP
The Vista error is similar.
Here is the page/message you get after acknowledging the error message:
In the lower right corner of the browsers, I noticed in vista something that I don't see in XP:
XP:
Vista:
What is this "Protected Mode: On"? In Vista, if I open up the "Security Properties" on toggle this off (This setting does not exist in IE7/XP), I am prompted to restart IE and then navigating to my Joomla Flash Uploader component works! I re-enabled this option and it still works!
IE7/XP does not have this option and I get the error every time(I suspect that it is related to Vista's more robust security....) Anyway, both zones are set to "Internet" which are at level "Medium-high".
What is it that might be triggering the security settings. These are IE's default settings and my users aren't smart enough to go in and modify these things on their own. Or add our site to their "Trusted Users" zone, etc. What other options do I have? Is something in the javascript causing this, can it be fixed?
I can't speak for my client, but just before I get the error message in IE7, it does start to render the Flash, and I can see the GUI part of it, but just before it finishes, I get the error.
Like everyone else, I don't experience this in Firefox or Safari (I am a Mac user), but I have a PC running on my Mac in a Sun Microsystems VirtualBox VM running XP/IE7 (then I have the one Vista machine too.)
