Class log does not exist in Laravel

Question

I'm managing a legacy project that uses Laravel 5.1 and php7, it is running in CentOS.

Right now I'm trying to run it in a test enviorment using ubuntu 14.04 and php5 or Centos with php7, but there's no way I can figure out why I'm getting this error when trying to run the project.

    PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Class log does not exist' in /var/www/html/versioned/software/track2/bootstrap/cache/compiled.php:1291\nStack trace:\n#0 
    /var/www/html/versioned/software/track2/bootstrap/cache/compiled.php(1291): ReflectionClass->__construct('log')\n#1

Site is working in production, and I have copied the exact same files

Env file:

server=localhost
APP_KEY=secret
key=secret
web_database=db1
web_username=root
web_password=pwd
admin_user=d32d32d233d2
padding_top=5% 

Answer 1

This might happen because you have a wrong value in one of the config files or spaces in your .env file.

If you need spaces in your .env file, use ENV_KEY='some value here' instead.
