PHPLIST電子報安裝時出現錯誤訊息 "Database error 1071 while doing query Specified key was too long; max key length is 1000 bytes"

1. 先開啟 /lists/admin/structure.php 
2. 先搜尋到 "user_blacklist_data" => array(　字串底下
3. 將varcher(255)改成varcher(233)，如下：
修改前：
"email" => array("varchar(255) not null unique","Email"),
修改後：
"email" => array("varchar(233) not null unique","Email"),
