I get this error when I edit a page…
Warning: Undefined array key “background-image” in /usr/www/users/vaandel/wp-content/themes/astra/inc/core/class-astra-wp-editor-css.php on line 325
I disabled al the plugins. Still there. Tried another theme and it goes away. Happens with either child or Main theme and no plugins.
]]>– in the WP backend, the Yoast Search Appearance tab is empty. The tabs at the top are showing, but no settings are showing at all
– the sitemap.xml is not correct. This includes all content types, including those that were set to hidden
– as a workaround, I rolled back the plugin version to v18.2 or v18.3. This fixes the issues and things work correctly again.
– WordPress sends the error report listed below:
Can you please advise how to fix this? Thanks!

Howdy!
Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.
In this case, WordPress caught an error with one of your plugins, Yoast SEO.
First, visit your website (https://castoredcstage.wpengine.com/) and check for any visible issues. Next, visit the page where the error was caught (https://castoredcstage.wpengine.com/wp-admin/admin.php?page=wpseo_titles) and check for any visible issues.
Please contact your host for assistance with investigating this issue further.
If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.
https://castoredcstage.wpengine.com/wp-login.php?action=enter_recovery_mode&rm_token=81aN3zTOeAETfA5A0sNBWz&rm_key=BB2KvzGQiFZoQmKLPjK8Pm
To keep your site safe, this link will expire in 1 day. Don’t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.
When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.8.3
Current theme: Castor EDC (version 3.8.0)
Current plugin: Yoast SEO (version 18.4.1)
PHP version 8.0.16

The preview works: No
It works with other themes: No
It works when I disable all other plugins: Haven’t Tried
Meta Slider version: 3.16.4
I can’t save any slideshow anymore, even a new one. It used to work a while ago. I removed all the theme files and it doesn’t work. The preview does load but it doesn’t reflect the content I provided.
