[pmwiki-users] recipe Captcha can not display image

Hi,

Oh, yes, it really matters!

I carefully checked the error image, and found there are 3 bytes in the
file header, which are the BOM of UTF-8.

Then I searched all php files with the following command and found the
config.php was transferred to UTF-8 with BOM:

grep -r -P "\xef\xbb\xbf" * --include=*.php

The reason why I transferred the config file is I wanted to customize the
title with my site's Chinese name.

It's finally fixed after 1 week. Thank you very much!

Best Regards,
Liu Chang
