I try to install the WPBakery Page Builder within Liquid on 2 servers served by Load balancer.

Installation sometimes cracks, and sometimes I manage to skip to the next step and I got error 500. Then I put these in wp-config.php to read the errors:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );

Then I reached step 3 "Import Content" but it produces so many errors, among others:

Required parameter $width follows optional parameter $attach_id in C:\inetpub\wwwroot\MediionWp\wp-content\plugins\liquid_js_composer\include\helpers\helpers.php

or

(C:\inetpub\wwwroot\MediionWp/wp-content/plugins/liquid_js_composer/js_composer.php): Failed to open stream: No such file or directory

the file really doesn't exist in the path above.

CodePudding user response：

After a while, I managed to solve it:

1. problem (Required parameter $width follows optional parameter $attach_id):

They wrote a function that accepts first optional parameters, then mandatory, which is strange, so instead of

function wpb_resize( $attach_id = null, $img_url = null, $width, $height, $crop = false )

I've put

function wpb_resize( $attach_id = null, $img_url = null, $width = 0, $height = 0, $crop = false )

2. problem (No such file or directory)

I took a file liquid_js_composer.php from the same directory and copied it named as js_composer.php because I suspect they forgot to rename it (or referenced a wrong file name)

So far so good, haven't noticed any more problems yet.
