Using Opera Browser 10.01 and Windows XP:

STARTING FROM tempIWTboard.

I normally keep it set at Show New Only (forums).

To get to a forum not shown, I click on Show all Forums:

When I click on that, I get this error message:

I can hit the back button, and it returns me to the forum list, but nothing has changed, it still shows new forums only.

The only way I have found to get around it and make those changes are these steps:
1) Hit Back Button
2) Exit IWT tab without logging out
3) Open new tab on taskbar and reopen IWT
4) Click on TempIWT
5) All forums are then displayed

It works this way with both issues: Changing threads viewed or changing forums viewed. Each time I select a new option for viewing I get this error message and have to repeat steps 1-5 in order to make those changes happen.

John reconfigured Opera to send the referrer header, and it is now working! It is a lot slower at the moment, but that might be unrelated. I'll test again tomorrow.
