Hello, I have following wiki website:
MediaWiki: 1.29.1
PHP:5.6.30 (cgi-fcgi)
MySQL: 5.6.35-81.0
So I have downloaded Flow, add extension to my LocalSettings.php file, run the update.php. And when I go to discussion page flow appears but when I add a topic it cannot be posted to discussion page, instead of it I see see this (when I click post message):
Could someone tell me how can I fix it? Thank you
