Greetings from South Korea! I'm operating a small mediawiki site in Korean.
Recently, I moved the server. Than, Flow extension stopped working.
Mediawiki says cannot connect to database, but all settings and pages views are working fine, only flow board is working incorrectly.
Looking for your help!
