Hey phazylgmai, 

It looks to me that the Mysql is not connected. Have you tried reviewing reviewing the mysql configuration in the env.php? 

We can definitely hop on a call if you'd like?

There can be couple of reasons. Look for the database connection details in <Magento root>/app/etc/env.php. Make sure you have correct details.

Make sure mysql is running on the server and you are able to connect mysql as well and Magento database using the credentials added in env.php file.

Hi, I'm actually working on an Amazon EC2 instance and I was trying to change the memory limit in php.ini, I may have altered the contents of the file incorrectly. I'm a newbie so is there any way I can replace the php.ini with a default file?

@phazylgmaiIf you have the backup then you can use it. If no backups then under PHP folder it normally provides an additional php.ini. If there is no additional php.ini then download one from internet.

You can compare both to find out where the issue is. Fix it and upload the fixed php.ini.
