[Theme: Virtue] Page 2 posts and calendar monthly archive error message

Hello there,

I have a website called https://www.lifeisbearygood.com. I moved my WordPress from https://www.lifeisbearygood.com/wordpress to this URL using the Codex instructions. I also used the Velvet Blues plugin to do a search and replace which solved most of my problems with the images not showing up after the URL change.

I still have a couple of problems with this site.

1) If I scroll to the bottom and click on any page beyond page 1, I get an internal server error. For example: https://lifeisbearygood.com/page/2/.

2) Monthly archive pages also get an internal server error (July 2014 is the only one that works for some reason). For example: https://lifeisbearygood.com/2014/06/

Does anyone have any ideas why this is not working? Does it have anything to do with permalinks?

Thanks for your help.
