Thread:Project:Support desk/Problem with columns

I am new to MediaWiki. Just installed latest on fresh CentOS 6.4 install. All software is current.

I am trying to get columns to work in my pages.

Using colbegin, div col, etc. seem to have no affect. I get a red "Template: Div Col" or similar instead of the markup.

I have copied MediaWiki:Common.css to my site thinking that would help but it seems to make no difference.

What have I missed?

Thanks!
