[speerio]

Hello,

Is the correct user with access rights added to the restored database in sql?

[Sheba]

Thanks for your response.

How do I check or assign correct user to database?

[speerio · Accepted solution]

On your webserver in the section MySQL databases, and the add user to database.
Check the user credentials in your env.php

[Sheba]

Thank you speerio! 

[speerio]

Sheba,

Glad that i could help.

[amitsamsukha]

try checking the user access rights for the database. to check the allowed database you can log in into

mysql -u username -p

SHOW DATABASES;

this will list out the databases for that user. 

if you can't see the database "holiday_dev" then check with your root user and assign this database to the user configured in app/etc/env.php

OR update the root user's credentials in env.php
