I installed WAMP server 2.4 the latest one on its website which currently support PHP 5.4 and Apache 2.4. This works successfully. When I tried to downgrade the PHP version to 5.2 or another lower version, the system rejected this downgrading saying my Apache version is not compatible. So, I tried downgrading my Apache version, but it said it couldn't because my PHP version isn't compatible... apparently I am looping without being able to downgrade the PHP. Is there any solution for this?. I would very much appreciate any help on this.
