Unable to install 1 click module

Hi everyone,
I've got trouble using the one click module install on web cloud hosting for wordpress.
Does anyone know how to fix this issue ? Tho it sound like an OVH related issue.

An error has occurred installing the Wordpress module on the web hosting plan linked to the centrov.xxxxxxx.hosting.ovh.net domain name.

The error message is as follows:

The centrovxxxx mysql database (centrovxxxx.mysql.db server) seems to be blocked in read and/or write mode for the centrovxxxx user. The module cannot be installed on it.
You must modify the rights for this user, or select another user.

Regards,
