WAMP PS9 not opening new installation

[barriekenyon]

I have a new installation of PS9.0.1 on a new Win 11 / WAMP setup.

PS9 Installs OK but then Apache refuses to serve up both the shop or the back end.

The installation is:

WAMP Server 2.4. Server Configuration

Apache Version: 2.4.65  - Documentation Apache - Loaded Apache modules

Server Software: Apache/2.4.65 (Win64) PHP/8.3.28 mod_fcgid/2.3.10-dev - Port defined for Apache: 80

PHP Version: [Apache module]  8.3.28 - Documentation PHP - Loaded PHP extensions - Use of PHP versions

MariaDB Version: 11.4.9 - Port defined for MariaDB: 3307 -  Documentation MariaDB - MySQL - MariaDB

Win64OpenSSL_Light-3_6_0 (1)

Opening https://localhost/PS produces:

Hmmm… can't reach this page

localhost refused to connect.

Try:

Checking the connection

Checking the proxy and the firewall

ERR_CONNECTION_REFUSED

And the back end produces:

Oops! An Error Occurred

The server returned a "500 Internal Server Error".

I am obviously new at this. What have I missed? Please help!! Very annoying
