Error

Semantic MediaWiki

Semantic MediaWiki was installed and enabled but is missing an appropriate upgrade key.

Version

Semantic MediaWiki:

3.2.0 (smw:2020-04-18)

MediaWiki:

1.34.1

Code:

ERROR_SCHEMA_INVALID_KEY

Why do I see this page?

Semantic MediaWiki's internal database structure has changed and requires some adjustments to be fully functional. There can be several reasons including:

Changes to the list of fixed properties and may require additional table(s)
Changes to the overall table structure or indices requirements
Changes to the selected storage or query engine
Changes to the required entity collation

How can I fix this error?

An administrator (or any person with administrator rights) has to run either MediaWiki's update.php or Semantic MediaWiki's setupStore.php maintenance script.
