Heads up..Latest udpate today killed site.

seems to work. Thank you

@anjamo If I understand correctly, Google Analytics works fine now and Yoast SEO won’t activate anymore? I recommend you delete the Yoast SEO folder and install it again via the plugins installer.

My solution is as omarreis said. Delete Yoast SEO using FTP or cPanel. This brought up my site again, so logged into wp-admin dashboard, and go to plugins and fully deleted Yoast.

Re-installed Yoast SEO again and all seem to work again.

If it still gives problems, there is probably a plugins clash and you need to eliminate Yoast or the clashing one. If all fails another SEO plugin could be tried – I’ve sucessfully used “FV Simpler SEO” in the past.

(For completion, my problem WAS: After updating Yoast SEO plugin, my WordPress site shows a white page with the message “Your PHP installation appears to be missing the MySQL extension which is required by WordPress.”)

Ok, so three different issues have been reported (by order of impact):

1) Fatal error: Call to a member function get() on a non-object in /domain/public_html/wp-includes/query.php on line 28

Reported: ~10 times

So far, we are unable to reproduce the issue. We would greatly appreciate a backtrace for this error. We think this is a plugin/theme conflict. We’d appreciate it if someone experiencing this error would disable all plugins except Yoast SEO and see if the issue still occurs. Please share plugin lists / themes used / PHP version / WordPress version.

2) Error: Call to undefined method Yoast_Api_Libs::load_api_libraries()

Reported: 3 times

The issue pops up in combination with versions of Google Analytics by Yoast older than 5.4.3. Can be solved by updating Google Analytics by Yoast to its latest version (currently 5.4.4)

3) “Your PHP installation appears to be missing the MySQL extension which is required by WordPress.”

Reported: 1 time

This seems to be completely unrelated to our plugin. Re-installing Yoast SEO seemed to have fixed the issue.

hi

I am running it fine, however the only difference is I don’t have the google analytics installed

thanks

For more advanced users experiencing this issue:

Here’s an article that can help you get a stacktrace: https://www.barrykooij.com/white-screen-wordpress/

We understand there is an issue with wp_query, but we are unsure what’s causing it. For that we need to see from where wp_query was called

I use PressCustomizr theme but this theme can not conflict with plugin because it is recomended plugin for this theme.

Really I don’t see any problem in my site. I am using WordPress multisite and all plugins are up to date. If anyone of you find any problem in WPMS then please please inform.

@everyone we’ve done a change that will hopefully solve your problem.

Would you be so kind to test the beta we’ve created for you?

You can download it here: https://uploads.yoast.nl/wordpress-seo-2.3.1-beta.zip

Confirmed working! Thank you!

@gaswirth Thank you for testing!

@everyone we’d appreciate more feedback!

It seems to work!
what is the reason?

Ok then, we are going to release the patch. Thanks @all for your input and cooporation.

Bottomline was us using WP_Query too early and other plugins depending on certain hooks in WP_Query which were not available yet.

I am getting “Fatal error: Class ‘WPSEO_Customizer’ not found” after upgrading, will report the bug formally but figured this notice belongs here as well.

I’ve also experienced problems after updating your plugin the past few months. Maybe stop releasing updates every other day?
