Hi Dejang,
I’m sorry for the error. Some of the HTML in the sidebar has gotten repeated which is causing the very narrow layout issue.
I have a feeling this is due to a plugin since this wouldn’t happen normally, but there are two things you can try to fix this.
First, you can delete Ignite and reinstall it. You won’t be able to delete it until you switch to another theme, and then it can be removed. It can then be reinstalled via the Appearance menu. I know that might sound like an alarming thing to do, but I promise you won’t lose any of your settings. The site will be exactly the same after Ignite is reinstalled (but hopefully with the sidebar fixed!).
Secondly, you can deactivate all plugins on the site temporarily. Then, you can then reactivate them one-by-one until the problem returns to find which plugin is causing it.

?Deactivating your plugins in this way won’t have any effect on their settings.
