Manager.php(13) : Undefined constant ‘YoastSEO_Vendor\RUCKUSING_BASE’

Hi,

We apologize for the difficulties the plugin is causing for you. We are not sure why that error is appearing. We would like some more information to help us troubleshoot and rule out or in certain things.

1. Can you confirm you are using the most recent Yoast SEO, v14.2? If you update, does the issue resolve?

2. Can you confirm you are using WordPress 5.4.1? You can check by clicking on the W in the top left and selecting About. If you need to update, please check with your host provider.?Please know that if you are using an older version of WordPress Core you may experience unexpected behavior with Yoast.?This guide explains more:?https://yoast.com/why-we-dont-support-old-wordpress-versions/.

3. Are all your non-Yoast plugins and themes also updated?

4. Verify your database has the: ALTER, CREATE, DELETE, INDEX, INSERT, SELECT, UPDATE, DROP permissions. These are required to create these tables in your database: wp_yoast_indexable, wp_yoast_indexable_hierarchy, wp_yoast_migrations, wp_yoast_primary_term. If you are not sure, your host provider can help.

5.?Can you confirm your server has all the right requirements?? If you are not sure, speak to your host provider. This guide explains more:?https://kb.yoast.com/kb/plugin-requirements/.

6. Can you tell me which DB_CHARSET and DB_COLLATION are set in your wp-config.php? If you are not sure, your host provider can help.
