MediaWiki internal error - MediaWiki-l

13 Jan 2020


      The error and backtrace shown below is thrown when trying to load the
system page 'Mediawiki:Sitenotice'. It is the result of a system upgrade
during  which the database was edited AFTER the database had been
updated, but BEFORE the new Mediawiki version installation scripts had
been installed. Since it was the only page affected, we have lived with
it through several further upgrades . However, it is becoming a pain not
to able to use sitenotice so I would like (try??) to fix it.
Any suggestions as to how I should go about this, since the page itself
can be neither edited, deleted or restored to an earlier version through
the Mediwiki user interface itself? Is there a maintenance script for
example that might do the trick? or am I faced with manual database editing?
Any suggestions / advice would be much appreciated
