Reply To: Sidebar doesn't work

Did you make any changes to your CSS? The line that is causing the issue is on line 4045 –

	.content,
	.site-header .widget-area {
		width: auto;
	}

By default it’s supposed to be 640px –

	.content,
	.site-header .widget-area {
		width: 640px;
	}

Try changing it back to 640px and it should work again.
