Hi,
I am very doubtful and surprised that you have this configuration:
[apacheoptions]
apacheUseOtherPort = "on"
apachePortUsed = "8083"
This is an option used when Apache can't use port 80 at all and this is not the case because with the last modification you just made to replace the Listen ...:8083 by Listen ....:80 Wampserver works perfectly.
I can only advise you to put back the original configuration:
[apacheoptions]
apacheUseOtherPort = "off"
apachePortUsed = "80"
To do Wampserver stopped.
