Thread:Project:Support desk/Cannot add statements in item page: wikibase-api-param-missing

Dear,

Hello. I'm very new about mediawiki and I made my project.(mysql 5.5.41, php 5.4.10, mediawiki 1.24.1)

I've installed mediawiki and wikibase and tried to add statement to an item I've created("Obama") but couldn't do it.

After clicking add button and I had entered property such as "height", I had expected value input box but there was spinning icon forever.

I tried to find out the reason by searching portals or checking help but couldn't figure it out why.

When I checked with chrome, I got the error message as below.

It shows param-missing but no idea about it... Could you kindly give me any advice to solve the problem, please?
