WordPress 網(wǎng)站后臺無法修改php文件，提示Scrape key check failed. Please try again.

通過對網(wǎng)上相關(guān)資料的研究，發(fā)現(xiàn)少數(shù)IDC廠家的虛擬主機在使用wordpress4.9以上版本wordpress的時候，有可能出現(xiàn)編輯php文件無法保存，提示Scrape key check failed. Please try again .的情況，

目前沒有很好的解決辦法，暫時找到的一種解決辦法是：

進wordpress網(wǎng)站根目錄，找到wp-admin/includes/file.php

下載到本地，找下以下兩行代碼中間的部分：大約從522行到641行，

開頭 ? if ( $is_active && 'php' === $extension ) {

結(jié)尾?return new WP_Error( 'php_error', $message, $result );

將其刪除即可解決問題，
