On windows host using ftp, Undefined array key "islink"

[antonmo]

Fresh install of wordpress 6.4.1
On windows host using ftp

steps to recreate:

1. Going to "sitehealth" page gives critical warning ftp credentials are missing for updates.

2. Google search suggested adding the following to the user added section of wp-config.php

   define('FTP_USER', 'USERNAME');
   define('FTP_PASS', 'PASSWORD');
   define('FTP_HOST', 'FTP.EXAMPLE.COM');
   

3. After this, go back to site health page. It is giving the following warnings repeatedly:

   Warning: Undefined array key 3 in C:\...\wp-admin\includes\class-ftp.php on line 457
   
   Warning: Undefined array key "islink" in C:\...\wp-admin\includes\class-wp-filesystem-ftpsockets.php on line 695
   
   Warning: Undefined array key "perms" in C:\...\wp-admin\includes\class-wp-filesystem-ftpsockets.php on line 700
   
   Warning: Undefined array key "islink" in C:\...\wp-admin\includes\class-wp-filesystem-ftpsockets.php on line 695

Thanks for opening your first ticket @antonmo!

Moving to 6.5 for visibility. I've removed the version since this code is from a few different versions but is all quite old. While seen on the site health screen, this is related to the filesystem API so updating the component.

This ticket was discussed during bug scrub and due to possible complications with the Filesystem API decided to move this to the next milestone.

This bug also needs to be reproduced to the point what causes the Fatal Error to occure.

Ad props to @costdev

Thanks @antonmo for reporting this. We reviewed this Ticket during a recent bug-scrub session. Here's the summary of the feedback received:

1. Can we please ask for more information, especially Windows OS version and FTP client?

Thank you.

Props to @khoipro

Cheers!

Hi @antonmo hope you're doing well, along with the above are you also able to provide the following:

1. What version of PHP you were using
2. Which guide you were following which told you to add those to your config
3. Full stack trace of the errors if possible, please make sure no confidential details are shared here.

Thanks.

I don't think this has to do with a specific FTP client. I think that this has to do with WordPress being configured to use FTP, which is the default behavior when your server is not configured to allow direct file writes.

@antonmo are you still experiencing this issue with the latest version of WordPress (currently 6.6.2)? If so, could you prove the additional details requested by @veryard?

I'm moving this back to Awaiting Review until there's enough information to reliably reproduce and investigate.
