Hi Chad. Thank you for responding.
From what you're saying, It's clear that you have no routine in the installation to handle postgres being distinct from mysql, and that is likely why it is failing. You might want to look into addressing that for the future, as postgres is not going anywhere, it's a much nicer database than mysql, and laravel supports it natively (so October should too by my reasoning).
I think I'm giving up on October for now. I'm finding myself fighting it trying to make it do what I want it to do and getting aggravated. I'm going to roll my own simple blog in straight Laravel which (paradoxically) will be less complicated I think.
I'd appreciate a refund if you can manage it, since I'm not going to be using the plugin. If that's against policy then improve ProBlog with it.
