Upgrade 2 to 3 Using Current Directory Structure

Question

I'm working on upgrading an existing Craft 2.6 site to Craft 3.0.3.1 on my development server with official documentation that was provided. I keep running into an Internal Server Error. I checked the logs and I'm looking to get pointed in the right direction if anyone has any tips. I checked other questions on this, and haven't seen anything specific to this issue.

Error logs:

Answer 1

This exactly what happened. Thank you for your help! This is the line that I added:

'initSQLs' => array("SET SESSION sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';") 

I was updating my sever environment and needed this for Craft 2.6 to work with MySQL 5.5 and higher. It was a work around that the Pixel & Tonic team provided awhile back. Thanks for pointing me in the right direction.
