vBulletin：标题和客户端库次要版本不匹配

Question

我已经转移了一个大型的vBulletin论坛，我复制了数据库和文件。 我已修改了要在数据库中访问的凭据，但收到错误.. 怎么解决？

mysql_connect(): Headers and client library minor version mismatch. Headers:50547 Library:100026
/var/www/vhosts/chorse.net/httpdocs/forum/includes/class_core.php on line 311

第311行：

if (function_exists('catch_db_error'))
{
set_error_handler('catch_db_error');
}

// catch_db_error will handle exiting, no infinite loop here
do
{
--->>>  $link = $this->functions[$usepconnect ? 'pconnect' : 'connect']("$servername:$port", $username, $password);
}
while ($link == false AND $this->reporterror);
