Topic on Extension talk:Wikibase Repository/Flow

For some reason, I get this error when I'm trying to create a new item through Special:NewItem. I searched this error in Google and found nothing. What am I downg wrong? ;(

I use:

MediaWiki 1.30.0

PHP 7.1.11 (apache2handler)

Wikibase Repository cc48ad1 (downloaded usign git)

I was following this instruction — Wikibase/Installation

Please help.

error log

It looks like the MediaWiki version you are using does not match the Wikibase version. The branch you are pointing to is from yesterday, while MediaWiki 1.30 is from December. The red box on Wikibase/Installation mentions this. You probably want to download Wikibase's REL1_30 branch.

It works, thanks a lot!
