  • Please make sure that you have 0777 permission to app/tmp (recursive)
  • Make sure that application is connecting to your mysql
  • Check app/tmp/logs/error.log file for additional information.

If application is logging the errors you should be able to see those errors in error.log file. You can share those logs here so we can help you better.

In case if database connection issue, you get error like below:

2024-01-24 16:14:05 Error: [MissingConnectionException] Database connection "Mysql" is missing, or could not be created.
Exception Attributes: array (
 'class' => 'Mysql',
 'message' => 'SQLSTATE[HY000] [1045] Access denied for user \'root\'@\'localhost\' (using password: YES)',
 'enabled' => true,
