impex_auth.php error

[Shpend]

Hi,

I just started moving my forum today from vBulletin 4 to vBulletin 3 .. I have installed vBulletin and did the config files for Impex, and uploaded. When I try and run impex I enter my customer number and see:

"
Warning: Cannot modify header information - headers already sent by (output started at /home/xxxx/public_html/forums/impex/ImpExConfig.php:1) in /home/xxx/public_html/forums/impex/impex_auth.php on line 22

any help please?

Impex does not support downgrading. You cannot use impex for this.

This error is not about downgrade but I see it when I click on Import button and
One of my friends has just tested passing to vb3 from vb 4 With Impex.
My Problem is that I can not Login into Impex.

Impex does not work for importing vB4 to vB3. Sorry.

[Shpend]

anyway thankyou friends but my question was not this.
I have the problem with impex .
If I want to import myBB it gives the same error.

Can you try re-downloading the ZIP file from the Members Area and re-upload all files (except install/install.php and includes/config.php.new) making sure you overwrite all files currently on your server.

Then restart your import.

Does this resolve the problem?

This error means you have a blank line or space at the beginning of your ImpxConfig.php file, or your text editor did not save this file correctly. If you do not see a blank space or line, then try a different text editor.
Make sure you save it in text format and upload in in ASCII format.
