Error wp-content/plugins/wordpress-seo/frontend/class-frontend.php:533

PHP message: PHP Warning: strpos(): Empty needle in /public_html/wp-content/plugins/wordpress-seo/frontend/class-frontend.php on line 533″

Hi @samisraeli,

We apologize for the inconvenience. We recently released Yoast SEO 9.0.3. If you update your plugin to the latest version, does the issue resolve? Also, can you confirm the PHP version you are running?

Hi @samisraeli,

This line has condition which checks constant ICL_LANGUAGE_CODE. Could you send more details about multi-language plugin (which could be source of this issue) and when you see this warning (which page/post/archive/… triggers this warning)?

Regards,
Sa?a

We recommend you try updating to Yoast SEO for WordPress v9.1 and then performing a conflict check to see if there is a conflicting plugin or theme.

1. Make sure the issue doesn’t persist when Yoast SEO is disabled.
2. Check for conflicts.
3. Check for JavaScript errors with your console.

If you find any JavaScript errors related to Yoast SEO or if there is a conflict with a plugin or a theme, you can create a new GitHub issue for our developers. Please report the issue to a third party developer as well.

If you didn’t find any conflicts or errors, we think the issue is specific to your site. We’d need to investigate further but are unable to do so on these forums. You can purchase Yoast SEO Premium and receive our Premium email support and we can help you further.

Thanks for understanding!
