Hello Dominique,

Thank you so much.  Yes, you are right, I am using text editor to edit the php file.  After seeing your respone, I downloaded a php editor, and I removed the strange character appearing before <?php

It is OK now.  Many thanks!

Thank also Rickard for this wonderful forum!

Thanks Rickard!!  I have checked but there is no whitespace before <?php at the beginning of the file.

I am using the Traditional Chinese language in the forum, and I have modified a bit the common.php in the language pack in order to suit my local circumstances.

Eveything seems fine, except that when I go to Administration, and then the Maintenance section, the following words appear at the top of the page:

Warning: Cannot modify header information - headers already sent by (output started at /home/httpd/vhosts/hkukatso50.org/httpdocs/bbs/lang/Traditional_Chinese/common.php:1) in /home/httpd/vhosts/hkukatso50.org/httpdocs/bbs/header.php on line 31

All other pages in the Administration looks fine.  Only when I go to the Maintenance section, the above sentences appear, and then the remaining maintenance page appears below the above sentences (with no obvious error).

What is the problem then?  Problem with the common.php or header.php?
Is that problem serious?  If not, I may leave it as it is, because only admin has access to that page.

Thanks in advance!

Matthew
