Yesterday, I uploaded the files of matomo in the public_html of my server with FileZilla.
In a folder called matomo.
When I want to open the url: https://www.thecementgrindingoffice.com/matomo/
I get the following error message:
Matomo encountered an error: No suitable convert encoding function (use UTF-8 as your encoding or install the iconv or mbstring extension). (which lead to: SQLSTATE[HY000]  Access denied for user ‘’@‘localhost’ (using password: NO))
Do you know the reason and what is the solution?
Thank you in advance for the help.
