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!
