I tried the introduction of piwik the following server .
When the creation of the database in this service , there are restrictions that would contain the “_” to the beginning of the database name .
Therefore, when the piwik installation , " the database name is not valid ", and did not perform the installation .
As a result of the inquiry to heteml, phenomenon has been confirmed , measures was that of the self- responsibility .
What possible installation in an environment that underscore enters the head of the database name ? Or is impossible to install environmentally , What Should I consider changing the server is faster ?
I am happy if you can the information of problem solving .
