New theme, Alternate 0

I asked this question in the Thought Mechanics forum, but there has been no answer, so I thought I’d try it out here:
Is there any easy way to make the sidebar show up on single post pages? Thanks in advance to anyone who knows.

It depends on your css a bit. If your single post pages (i.e., single.php or page.php), have a different div container than the index, just adding a call to the sidebar may cause an issue because of sizing. But, those issues aside, you should be able to simply add php get_sidebar(); to the single.php page.
