I logged on to the Wordpress account of a client to review and proofread a draft of a post one more time before publishing, and the Yoast meta box is blank. Not just for this one draft, but for all posts within this Wordpress account.
This is a screenshot of what I'm seeing:

- [ ] Classic Editor

Error Messages
Here is a screenshot of the error messages I am seeing:

It looks like there is some kind of issue with the Avada theme? Not sure.
Any help or suggestions are very much appreciated! Thank you!
Have you done the standard plugin conflict check?
I forgot to do that. Thank you for pointing that out!
After having done the plugin conflict check, the issue appears to be this plugin:
Fusion Core plugin
ThemeFusion Core Plugin for ThemeFusion Themes
Version 1.7.5.1
From what I can gather from the information you've provided I don't think this issue is caused by our plugin, but by Avada. Looking at the version numbers in your screenshot it looks like Avada is outdated, can you verify that you're running the latest version of the theme and its plugins?
You're correct -- it looks like Avada is out of date. I will pass this info back to the client. Thank you!
I have the same problem after the last update...

I had this exact same issue...
I traced it back to my child theme and a function I had in there to defer parsing of my js using:
function defer_parsing_of_js ( $url ) {
if ( FALSE === strpos( $url, '.js' ) ) return $url;
if ( strpos( $url, 'jquery.js' ) ) return $url;
return "$url' defer ";
}
add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );
To fix the issue all I had to do was exclude all the admin pages by adding:
if (!(is_admin() )) { and then closing it at the end } so the code should look like this:
if (!(is_admin() )) {
function defer_parsing_of_js ( $url ) {
if ( FALSE === strpos( $url, '.js' ) ) return $url;
if ( strpos( $url, 'jquery.js' ) ) return $url;
return "$url' defer ";
}
add_filter( 'clean_url', 'defer_parsing_of_js', 11, 1 );
}
Everything was working fine after that.
I hope that helps!!!!
Same problem here. I need to do more test to find if there is a conflict, but it was working fine until the update this morning to 11.5 (from 11.3)
So even if it is a conflict, something has changed on the plugin now.
Rolling back to 11.3 does not fix the issue, which is weird.
My issue was with the AMP 1.2 plugin too. In case it helps someone.

you're right, I checked it carefully and it's AMP 1.2 fault...

Looks like the fix was working and is merged. According to https://github.com/ampproject/amp-wp/pull/2688 the fix will be in the AMP 1.2.1 release. I will close this thread now as I believe the issue is known and fixed by a third party. If the problem persists after updating AMP to 1.2.1, please do leave a comment and we'll investigate further.
