Hi,
It is your understanding that is somewhat "weak".
Wampserver, like almost all servers, is Apache, PHP, Mysql and/or MariaDB, plus some applications like PHpMyAdmin.
As long as the Wampmanager icon is green and access to localhost and PhpMyAdmin is not a problem, this means that Wampserver is functional.
Then, the installation of CMS or web applications is YOUR responsibility.
PHP coding and SQL queries are also YOUR responsibility.
Now, if you don't want to read the documentation, or make any effort to learn, it's YOUR responsibility there too.
If you wait until everything is ready, without trying to learn and even less to understand, you are not on the right forum which is reserved for questions related to the correct functioning of the server (Green Icon and access to localhost and PhpMyAdmin).
You can uninstall Wampserver and change servers to see if the grass is greener elsewhere.
This discussion will be closed, but if you have questions about how the Wampserver works, you can open a new discussion, starting by answering:
