升級php版本後開啟松鼠郵件，只有空白頁出現error 500錯誤，去查詢log發現有以下訊息
[Sat Mar 23 16:09:18 2013] [error] [client 192.168.1.1] PHP Fatal error: Cannot redeclare hex2bin() in /usr/share/squirrelmail/plugins/mail_fetch/functions.php on line 104這個問題只需要重新命名所有的hex2bin 改成 convertHex2bin
vi /usr/share/squirrelmail/plugins/mail_fetch/functions.php
FILE /usr/local/www/squirrelmail/plugins/mail_fetch/functions.php
LINE 94 function convertHex2bin( $data ) {
FILE /usr/local/www/squirrelmail/plugins/mail_fetch/functions.php
LINE 138 $txt = mf_keyED(convertHex2bin( $txt ) );
或是使用sed指令取代所有的Rename all with sed
sed -i 's/hex2bin/convertHex2bin/g' /usr/share/squirrelmail/plugins/mail_fetch/functions.php
