Wordpress致命错误：未捕获错误：在/wp-includes/wp-db.php:1570中调用未定义函数mysql_connect（）

Question

我有大麻烦了。我安装了一个运输插件的空版本，我发现它和我的需求不相关，就删除了插件区域插件。删除那个插件后，我的网站就瘫痪了。它不断地向我显示致命的错误：

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/dev/public_html/new/wp-includes/wp-db.php:1570 Stack trace: #0 /home/dev/public_html/new/wp-includes/wp-db.php(658): wpdb->db_connect() #1 /home/dev/public_html/new/wp-includes/load.php(404): wpdb->__construct('dev_test', '3CrSPh8o766F', 'dev_test_ne...', 'localhost') #2 /home/dev/public_html/new/wp-settings.php(107): require_wp_db() #3 /home/dev/public_html/new/wp-config.php(82): require_once('/home/dev/p...') #4 /home/dev/public_html/new/wp-load.php(37): require_once('/home/dev/p...') #5 /home/dev/public_html/new/wp-blog-header.php(13): require_once('/home/dev/p...') #6 /home/dev/public_html/new/index.php(17): require('/home/dev/p...') #7 {main} thrown in /home/dev/public_html/new/wp-includes/wp-db.php on line 1570

我尝试替换除 wp-config.php 和 wp-content 文件夹之外的所有核心文件，但仍然出现同样的错误。此外，我尝试重新命名插件文件夹，但还是有错误。你们能告诉我怎样才能把我的网站要回来吗？

The error seems be simple, mysql_* functions are not enabled. Check with phpinfo() if these functions are truly disabled, and if yes, enable it. If no, there are some problems in the code that you are using, but if you have replaced all files as you write, is most probably the first option.
