If you are encountering some issues, first the best is to check the server and application logs. e.q /var/log/apache2/error.log and storage/logs/laravel.log

Also, it's recommended while debugging an issue, to set debug mode in the .env file, APP_DEBUG=true, read more about editing the .env file.

404 Not Found Error

Make sure that your subdomain ROOT Document points to /path/to/concord/public folder and not /path/to/concord folder.

Cannot see a folder named install

The URL /install is a Laravel route and not a folder. You will be redirected to /install if the application detects that the app needs to be installed.

Database connection/migration failed

If you are getting error message “Database connection/migration failed” and all database credentials are correct, check that your database user has enough privileges to perform database actions, Concord CRM database should be empty or your password contains a #(Hash).

Try one of the following commands:

php -d register_argc_argv=1 /path/to/concord/artisan schedule:run >/dev/null

Make sure to replace /path/to/concord/ with the path to your installation. On some shared hostings you may need to specify full path to the PHP executable (for example, /usr/local/bin/php-8.1 instead of php)
