I installed Semantic according to the installation manual, but when I visit my site I get this error: Semantic MediaWiki was installed and enabled but is missing an appropriate upgrade 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.

How can I solve it please?
The mediawiki version I'm using is 1.38.2
