Hi,
I have set the Nickel theme as the default one. It works fine with two columns and a small post cover on the left, but sometimes it behaves wrongly and shows just one column with the post cover filling the whole width of the post, either in the frontpage listing and in the post page. This occurs spontaneously without an action on my part. So far, I can temporarily solve this from the backend by cleaning the cache, but there should be another way -I hope.
Thank you.
