@context This forum is fine for support. For your issue, you probably left force SSL checked during install and your HTTP server does not have SSL support. The easiest fix is to open config.php and change:
If you are not comfortable doing that, you can delete config.php and start over however make sure to uncheck force SSL. I will push an update to change the “default” behavior, since that is a reoccurring problem.
Edit: Went ahead and pushed the update to install.php. Force SSL is unchecked by default now.
