Database schema out of sync - missing cl_collation column

[magent-cryptograss]

Problem

Category queries failing with:

Error 1054: Unknown column 'cl_collation' in 'SELECT'

This affects:

• Category pages not listing their members
• SMW queries that use categories
• Likely the reason newly created venue pages aren't showing up in queries

Cause

MediaWiki was upgraded but maintenance/update.php wasn't run to update the database schema.

Fix

SSH to PickiPedia server and run:

cd /path/to/mediawiki
php maintenance/update.php

Context

Discovered while creating St. Petersburg scene + 13 venue pages. The pages exist but category/SMW queries return empty or error.
