Since the last update, the content optimization tab is not functioning and the traffic lights are not working. I have checked the readability analysis functions for the plugin and as a Wordpress user, are enabled.
As a result I cannot use the optimisation tab at all. In addition, I have a warning flag that my homepage cannot be indexed by search engines.
Here is a screenshot of the Yoast SEO box

Could you please check for any JavaScript errors in your browser?
If you are unsure how to do so, you can find instructions here:

https://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors
Did you check Settings -> Reading ? There are check box "Search Engine Visibility". ( https://kb.yoast.com/kb/how-do-i-noindex-urls/#site )
Same probleme. But, since the last update, the content optimization tab is not functioning and the traffic lights are not working. I can not describe my articles
@Sarrus36D @juliesfamilykitchen Could you please check browser console? Do you see any JS error?
Without more details, it isn't possible to give any advice. I see that @juliesfamilykitchen checked all options except WP Dashboard ->Settings -> Reading ( https://kb.yoast.com/kb/how-do-i-noindex-urls/#site ). I can't reproduce similar behavior.
Did you check plugin conflicts?

Hi, I have the same issue as I cannot see or optimize the traffic light. Its not browser specific and I already checked for JavaScript errors in one of my browsers. This is what the js-console in Chrome told me:
JQMIGRATE: Migrate is installed, version 1.4.1
2wp-seo-post-scraper-561.min.js Failed to load resource: the server responded with a status of 500 (Internal Server Error)
post.php?post=30268&action=edit:1

Hi all.
Same problem here with the last version of WordPress SEO and WordPress.
Traffic lights and Content Analysis not work but other features working fine like progress bar of the title and meta, etc.

The Javascript console is clean:

We use server side Pagespeed optimization with Apache Mod_Pagespeed but also disabling it the problem persists.
We checked also all the http request with Fiddler but there aren't errors and all the js and css of wordpress-seo are correctly loaded.
Here the screenshot of all request containing "wordpress-seo":

Thanks
Best regards
Last update of Yoast fix the problem. Thanks
I updated to the latest version and the problem still persists:


I have the same problem. I have changed nothing just opened up WP and Yeost content optimization not working.

I am experiencing the same issue after updating to the latest version (7.6) of Yoast SEO this morning. Any tips what can I do to fix that?

Thanks for your time. Looking forward to a feedback!
Same here since this morning. wp-seo-post-scraper-760.min.js?ver=7.6:33 Uncaught TypeError: t.val is not a function
I am also expericing the EXACT same issue as @bangelov90 -- His screenshot is basically how mine looks like so I won't upload another.
This issue has also been reported over at wordpress.org's support forums by other in the last 48 hours or so. So it seems like it's a bug.
I have the same issue since this morning - with this error in the console: wp-seo-post-scraper-760.min
Update - I tested my plugins and it seems like my Custom Permalinks plugin is causing the issue. Does anyone else use this? I've raised a new bug report since this one is closed.
I confirm this a conflict with custom permalink. well done @eluxton
I can also confirm it is a conflict with custom permalink plugin. Good find!! Now who fixes it? Custom Permalinks or Yoast?
I also raised the issue with Custom Permalinks here: https://wordpress.org/support/topic/compatibility-with-yoast-seo-3/#post-10371371
Apparently the issue is due to a typo in the JS field of the updated Yoast plugin so they should fix it. I raised a new bug report and hopefully they will resolve it soon!
Here is the bug report I filed to Yoast - https://github.com/Yoast/wordpress-seo/issues/9966
Guilty :
add_filter( 'get_sample_permalink_html',
array( $this, 'custom_permalinks_get_sample_permalink_html' ), 10, 4
);
maybe it could be just commented out as a hotfix. It affects the form in backend, but should not break urls
Hello, I meet the same problem, who can help me?

Hello, I meet the same problem, who can help me?
I am having this same issue on Wordpress 5.02. disabling other plugins does not resolve. Any known plugin not compatible?
I'm having the exact 100% same issue. Looking at older threads this has been happening for more than 4 months. No change and no answer on any thread even though many have been opened.

Hi and thanks for the fast reply.
Yoast was updated to the latest version when this issue occurred (9.5).
The issue was caused by a conflict with the WPML plugin - at least in my case.
WPML didn't see the website key as valid so I had to Unregister and then Register my key again. I didn't know this because it looked "registered".
Hi, I have the same problem. Yoast is not showing any details at all.
I've de-installed all plugins and still no change. Anyone got any ideas?
I don't use a custom permalink either, just the standard Post Name structure

Also happening for me.
Disabled every plugin except for Yoast.
Running WordPress 5.1, Yoast 9.7
I have also checked for theme conflicts by changing the theme to 2015
