Can someone help me solve for this error message: An exception has been thrown during the rendering of a template ("Craft can't connect to the database with the credentials in craft/config/db.php.") in "components/site-header/_site-header" at line 23.
I am not a developer and can't seem to access back-end of site, either.
This is error message I received there when trying to log in:
Craft can’t connect to the database with the credentials in craft/config/db.php. The above error occurred when the Web server was processing your request. If you think this is a server error, please contact the webmaster. Thank you.
I am afraid I don't know where to start!
