Xibo on web hosting !?

Hello, I’m new on this forum. I am a teacher in a school (France) and I plan to set up a dynamic display solution. I found Xibo good for my objective.

I tried to install xibo on a web hosting and I can not.
I have this error at the startup installation.

Could not connect to MySQL with the administrator details. Please check and try again. Error Message = [SQLSTATE[HY000] [1044] Access denied for user ‘havacons_xibo’@‘localhost’ to database ‘havacons_xibo’]


Hops!, very sorry
I made an error on the user.
I did it yesterday late at night
