Migration stuck at Restoring Files

@adrianvergin

It looks like the new site is using PHP v7
Is your old site also using PHP v7? If not, I recommend you to use the same version of PHP as the original site and try to import again.

You can see this problem when some plugins or theme do not support PHP v7 – unfortunately, as of this moment, there is a large number of plugins that do not work under PHP v7.

Hi @yaniiliev

Thanks for your quick response. The old site is “Running PHP version: 7.0.18”. The error I’m getting implies that if I specify a different path in wp-stack-cache.php on line 21 I might be able to get into the admin panel but that doesn’t help me with the remaining 8% of files which were not restored…

Is there any way to find out what the offending plugin actually is? I can’t find anything to do with wp-stack-cache under installed plugins. Is there anywhere else the migration generates logs if it doesn’t think it encountered an error?

Cheers
Adrian

The log file is in wp-content/plugins/all-in-one-wp-migration/storage/error.log

Try to disable all caching plugins before export.
Look into wp-content/mu-plugins – you may have a caching plugin in there too.

Hi @yaniiliev

In the wp-content/plugins/all-in-one-wp-migration/storage/ folder I’ve only got the following:
m8c6kvg8hdlw (folder)
index.php (file)

Either the permissions on error.log won’t let me see the file when browsing the folder or it doesn’t exists.

Under wp-content/mu-plugins I’ve got:
1and1-subdomain.php
wp-stack-cache.php

The 1and1-subdomain.php file doesn’t exist on the old site so I’m wondering if maybe the two files in there might be trying to perform the same function.

I did some more digging on the old site and managed to find the “StackCache” plugin in the installed plugins list on the old site. Curiously, it’s not visible when you filter by All but it does come up when you filter by Must-Use.

The plugin description reads:

StackCache
Wrapper to include the Stack Cache Plugin Library
By Stack CP | Visit plugin site (https://cache.stackcp.com/)

There are no options to disable it and the plugin website doesn’t exist so I can’t access any documentation.

Please pardon my ignorance as I’m a relatively new WordPress user but how can I disable a plugin which doesn’t have the “deactivate” option? Is there any way to select which plugins to restore within AIO WP Migration?

Cheers
Adrian

Hey @yaniiliev, I’ve been trying to migrate my website from one domain on one contract with my host (1&1) to another domain on a different contract. I’ve made sure that the PHP versions of both are the same.

So I’m able to export .wpress files from the source website but when I try to import a file to my new domain, the process times out at

“Restoring X files…
Y% complete”

I have to stop the process and when I go my new domain’s WP admin page, it reads

Fatal error: Cannot declare class Product_Subdomains, because the name is already in use in …/wp-content/mu-plugins/product-domain.php on line 12

The problem occurs at a hosting plugin?

<?php
/*
Plugin Name: Product Subdomain
Plugin URI: https://1and1.com
Description: Handles our product subdomains
*/
if ( ! defined( ‘ABSPATH’ ) ) {
die();
}
class Product_Subdomains { <– Something happens here
…
}
new Product_Subdomains;

I’m a newbie and would love to take care of this soon, so any feedback would be appreciated. Thank you.

I am facing an issue while migrating the website from one domain to 2 different domain.
website actual PHP version is 5.6
1. Php version 5.4
2. Php version 7

But the issue is that
1. on version 5.4 it is stuck at 16% during restoring of files
2. on version 7 it is stuck at 92% during restoring of files

What should I do now.
