Arun Basil Lal on ""Error establishing a database connection" | Please help me out"

I'll start by saying that I don't know squat about coding, hosting, or any of that stuff. I was using a video and I basically followed everything, from 000webhost to FileZilla. I was all fine until I got to the part where you set up the database with WordPress.
Here are a few things I don't want suggested to me:

• Anything with the wp-config file. I do NOT have that, just the sample one.
• Anything that has to do with incorrectly spelled useames, passwords, or hosts. I have checked that MANY times.
• Anything that has to do with me having an already-existing website/domain (or linking to it). I have neither of those, as I am starting from scratch here. All I have is an account, a database, and increasing frustration.

Do you think it could be because of the fact that I'm using a free hosting service? If anyone has any suggestions/solutions, PLEASE speak up. I'm very anxious to start this site. Thanks in advance!

You need a wp-config.php file for WordPress to work.

Copy your wp-config-sample.php and name the copy as wp-config.php in the same folder.

Anything that has to do with incorrectly spelled useames, passwords, or hosts. I have checked that MANY times.

From this, I am assuming you filled up your wp-config-sample. Once you have made the copy and named it as wp-config, your website should work.

Good luck.
