Hi together,

one of our users mailed me that when he tries to open our forum (RC5) with IE, he gets the following error message:

-----------------------------------------------
Error 403
We're sorry, but we could not fulfill your request for /index.php?mode=page&id=1 on this server.

You can use this key to fix this problem yourself.
If you are unable to fix the problem yourself, please contact badbots at ioerror.us and be sure to provide the technical support key shown above.
-----------------------------------------------

RC5 is installed 3 weeks ago, he gets this message since last week.
Antivirus and Spybot find nothing, clearing his IE-Cache also gives no result.
With FF the forum works fine.

Could you help us?

Thanks,
Stefan
