Struggle setting up processwire on OVH

[Clemtre]

I'm designing a portfolio website for a friend with a bit of p5. Adapting the css to all device formats and pixel density is driving me crazy so I'd like to use a CMS

Website and sql database are hosted on the same domain at OVH

When I try to set up processwire, I get this error message

 

 

Here is the sql database I use (I have no idea if these informations are confidential)

I understand this post might be cringeworthy as I'm completely noob to this domain, my apologies.

Thanks a lot for your help

Well, DB-user and host are wrong. Just compare the two screenshots...
