So I've got my backdrop raw install, with some contrib module files added. When I change the settings.php to point to my Drupal 7 database so I can convert it, I get an HTTP 500 error. In my MySQL Workbench, I can query both databases. I did a grant all command on the Drupal database for the database user that accesses the raw backdrop database, so am assuming the rest of the $database spec in settings.php should work, right?
If I go into index.php and comment out the code and put in echo 'Hello world'; it prints. The define and include statements work. Uncommenting the backdrop_bootstrap results in the HTTP 500 error. It is inside of _backdrop_bootstrap_full where I am getting this error.
If anybody has any hints on how I can debug this, it would be appreciated. The site is an intranet in a private network. What I don't understand is why I'm getting the 500 instead of a specific error, especially since the bootstrap has a try/catch. I added these to settings.php:
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
