How to go to the config file?
Can you help me to give me the steps on how to fix the error?
Thank you
Inside the project's config file, you'll need to make changes under the "Database Information"
Please have a look at DATABASE _ USER, DATABASE _ PASS. (by default the DATABASE _ PASS field is empty and seems like you've your own password for that, so please fill it out!)
I already changed the config file and still have the same error message.
You have to replace your server's username and password with the existing one! Also, you might have a different port number (if so replace
localhost
withlocalhost:[YOUR_PORT_NUMBER]
). That's the only problem for you [according to your mentioned error message].200: undefined

Please check your database connection!
there is a bug
I think It actually requires To Load jQuery before loading bootstrap.
But how to do that💀
under which section?
below are the modifications to the database. i can now see the login screen but can't access the application even when using this credential admin Password@123. I even added another user in the database with another password but still.
// DATABASE INFORMATION
define('DATABASE_HOST', 'localhost');
define('DATABASE_NAME', 'invoicemgsys');
define('DATABASE_USER', 'root');
define('DATABASE_PASS', 'Application');
can't access the application..? any specific error messages?
The forgot.php file is not available in the project, error 200: undefined when connecting if I check the remember me option, Error: An error has occurred, please try again while creating invoice.
Regarding warning message "Please try again..." is caused due to your LATEST PHP version. But still, you can find your invoices made under the manage invoice section. Besides, other [forgot file] is probably left out by the developer.
