Error Establishing a Database Connection

Hey everyone,

I just started using www.remarpro.com, and I desperately need some help with the installation. I managed to successfully install WordPress on my personal computer, but need to do so on my company’s computer.

However, in spite of doing the exact same things as on my personal computer, the installation keeps spitting up the same error message:

I’ve tried a number of ways of fixing the issue, but none seemed to have worked. Could someone please help me?

Thanks in advance!
