IE6 blank php websites

[Wijono]

Of a sudden in one of the PC running IE6 under the WinXP SP2, most of the php websites will end up with a blank white screen, even though the status bar said “Done”, that include this MSFN website. What could have gone wrong? What could be the cure?

Thanks a lot.

At the beginning I thought it was only php. But it turns out that not only php websites that end up with blank screen, some non-php sites also end up with white screen! And some php sites can be opened with no problem. Any clue to that annoying situation??

I was thinking that the problem was somehow caused by the Internet Restricted Sites.

So I deleted the contents of following registry keys related to the Restricted Sites:

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History]

[HKEY_USERS\.DEFAULT\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History]

[HKEY_USERS\S-1-5-18\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History]

[HKEY_USERS\S-1-5-19\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History]

[HKEY_USERS\S-1-5-20\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]

[HKEY_USERS\.DEFAULT\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]

[HKEY_USERS\S-1-5-18\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]

[HKEY_USERS\S-1-5-19\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]

[HKEY_USERS\S-1-5-20\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains]

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]

[HKEY_USERS\.DEFAULT\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]

[HKEY_USERS\S-1-5-18\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]

[HKEY_USERS\S-1-5-19\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]

[HKEY_USERS\S-1-5-20\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges]

The result is negative though. I still cannot open many websites, including MSFN from that PC!

Then I set the value of "Security_HKLM_only" in the following registry key to 1:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings]

Of a sudden I can normally open those websites that were blank screen before!!

I know it is not a proper fix. Hence I would highly appreciate for any hint or anything that can point me to the proper solution.
