Yoast database schema errors on first page load after importing clean dump

[sun]

Problem

• After importing a clean database dump of a site that has the Yoast wordpress-seo plugin enabled, the following errors appear on the first page load (but disappear afterwards).

Details

• Most likely we are removing an option that stores the last database schema version. Without it, the plugin attempts to reinstall or update its tables.

Proposed solution

1. Identify which option needs to be kept and ensure that it is retained in the clean database dump.
