升級很容易就卡，升級不了。

PHP 版本為 7.2，Divi 主題版本為 3.21.1

[nanfeng]

在本地電腦用 phpStudy 搭建網站，Divi 主題啟動視覺編輯器也很慢 （配置按 System Status 的要求配置了），選 php7.2 的。

按下面的要求配置了

System Status

post_max_size

8M – We recommend 64M for the best experience.

max_execution_time

30 – We recommend 180 for the best experience.

upload_max_filesize

2M – We recommend 64M for the best experience.

max_input_time

60 – We recommend 180 for the best experience.

max_input_vars

1000 – We recommend 3000 for the best experience.

 

也配置了 Wordpress 的 default-constants.php 檔案:

default-constants.php 路徑： /wp-includes/default-constants.php

大概在 45,47,57 行處分別修改如下

WP_MEMORY_LIMIT

WP_MEMORY_LIMIT

WP_MAX_MEMORY_LIMIT

 

// Define memory limits.

if ( ! defined( ‘WP_MEMORY_LIMIT’ ) ) {

if ( false === wp_is_ini_value_changeable( ‘memory_limit’ ) ) {

define( ‘WP_MEMORY_LIMIT’, $current_limit );

} elseif ( is_multisite() ) {

define( ‘WP_MEMORY_LIMIT’, ‘256M’ );

} else {

define( ‘WP_MEMORY_LIMIT’, ‘256M’ );

}

}

 

if ( ! defined( ‘WP_MAX_MEMORY_LIMIT’ ) ) {

if ( false === wp_is_ini_value_changeable( ‘memory_limit’ ) ) {

define( ‘WP_MAX_MEMORY_LIMIT’, $current_limit );

} elseif ( -1 === $current_limit_int || $current_limit_int > 268435456 /* = 256M */ ) {

define( ‘WP_MAX_MEMORY_LIMIT’, $current_limit );

} else {

define( ‘WP_MAX_MEMORY_LIMIT’, ‘512M’ );

}

}

Divi 主題啟動視覺編輯器每次都很慢，新建頁面啟動視覺編輯器每次啟動要幾分鐘，修改頁面啟動視覺編輯器要一分多鐘 （有時也要幾分鐘），相關的設定也根據 support center 設定了相關的引數了，Wordpress 也把記憶體設定分別為 256M，256M，512M 了，啟動還是太慢。若是在其它主題，比如 Avada 中安裝 Divi builder 外掛, 新建頁面啟動 Divi builder 的視覺編輯器只需要大概 10 秒鐘左右，勉強能接收。 Divi 主題整合 Divi builder，速度應該更加快才對啊。到底是什麼問題呢？虛擬主機是西部數碼 （west.cn) 上購買的美國增強型虛擬主機。
