如何找出WordPress主题为什么会破坏我的网站？

Question

我最近在WordPress上有了一个主题，在设置主题时我试图使用Twitter功能，虽然这部分代码可以将我的一条推文嵌入到页面中，但这会破坏网站。

所有的API令牌都已添加到代码的前面部分，这让我觉得有些错误，并且可能存在语法错误。

 <?php
            function buildBaseString($baseURI, $method, $params) {
                $r = array();
                ksort($params);
                foreach($params as $key=>$value){
                    $r[] = "$key=" . rawurlencode($value);
                }
                return $method."&" . rawurlencode($baseURI) . '&' . rawurlencode(implode('&', $r));
            }

            function buildAuthorizationHeader($oauth) {
                $r = 'Authorization: OAuth ';
