I'm trying to upgrade a v2 site to v3 and have done the following:
- Verified that my server meets the v3 requirements using the Craft Server Check.
- Followed steps 1-3 on this page.
- Followed the directions on this page.
When I go to my control panel's URL, I get the following error: "An internal server error occurred." There's nothing in my server's "error.log" file.
As a test, I even created a fresh install of v2 on a new server instance, imported my site's data, and tried upgrading that, and I still get the server error.
FWIW, I'm running Apache 2.4, Ubuntu 16.04, PHP 7.0.30, and MySQL v5.7.22.
