Fout

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

Release

3.1.6 (smw:2019-09-23)

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:

• Additional fixed properties (requires additional table setup) were added
• An upgrade contains some changes to tables or indices making an interception obligatory before accessing the data
• Changes to the storage or query engine

How do 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.
