Posts folder is not being created

I’m running into an issue with my blog /posts folder. I have switched servers, and after republishing the files I get the pop-up which says that that /posts folder does not exist and therefore was made. Unfortunately, no post folder is made. I’m running a new installation on AWS lightsail configured with lamp PHP 7 bitnami server. My username (entered on the rapidweaver publishing page) has administrative rights with the server.
We also tried directly creating a posts folder on the server, and tried adding a blog post using the editor page- also unsuccessful.
Any help getting my blog up and running would be greatly appreciated!
