WordPress 5.3 compatibility

[nuclearpengy]

WordPress 5.3 is scheduled to be released on 12 November 2019. Test the plugin with WordPress 5.3 and ensure it's compatible.

Areas to focus on:

1. Admin CSS changes and recommendations (https://make.wordpress.org/core/2019/10/18/noteworthy-admin-css-changes-in-wordpress-5-3/) as well as the reduction of block editor CSS (https://make.wordpress.org/core/2019/09/27/block-editor-theme-related-updates-in-wordpress-5-3/).
2. Changes to the WP_MS_Sites_List_Table class: https://make.wordpress.org/core/2019/10/15/enhancements-to-the-network-sites-screen-in-wordpress-5-3/.
3. Potential impact if a plugin extends certain classes and overloads certain methods in the spread operator: https://make.wordpress.org/core/2019/10/09/wp-5-3-introducing-the-spread-operator/.
4. Support for PHP 7.4 and recommendation to add the PHPCompatibility checker to help detect PHP version compatibility issues in PHP 7.4: https://make.wordpress.org/core/2019/10/11/wordpress-and-php-7-4/.
5. Changes to wp_die(): https://make.wordpress.org/core/2019/10/15/changes-to-wp_die-html-output-in-wordpress-5-3/.

Any ETA on this? I just tried to install the plug in on a client's WP 5.3.2 install and it failed with:
The plugin ghost/ghost.php has been deactivated due to an error: Plugin file does not exist.

hi @jameshome - The current version is working with 5.3.2. I just need to check a few things before resolving/closing this issue.

Did you download this version https://wordpress.org/plugins/ghost/ ?

Actually, I have the plugin installed in version 5.3.2, and when I click on the "zip" or "json" links, I get presented with a white screen, and nothing else happens.

Is there any plugin that could collide with this one?

@nuclearpengy thanks for the quick response and sorry I entirely missed it until now!

I did indeed try to install that version. I tried several times and had no luck. I moved on to another part of the project and promptly forgot all about it until Friday, when I tried again and it installed just fine. Yay!

Unfortunately, it would neither give me the zip or json files, instead erroring with a Wordpress fatal. Boo.

I don't presently have access to the Wordpress debug logs, so your guess is better than mine what the problem is, but that seems like it's my problem to deal with and unlikely to be a plug-in bug. Thanks again!

@jameshome hi, for some reason it worked.

The changes I made were to activate php 7.4, and disable 7.3. For some reason, the zip file just worked as expected,
