Using a plugin in a page

I have installed the page-inject plugin. When I add "[plugin:page-inject] (/route/to/page)" in to my page. It is displayed as a normal link to another page. What am I doing wrong? (I had to put a space in between in else you see it as a link here too)

Are you sure you have installed the plugin correctly? Are you sure you have entered the Markdown link correctly? In your code above there is a space between the ] and the (. it should have none:

[plugin:page-inject](/route/to/page)
