hi Im not understanding this one setting for paid membership pro and w3 total cache plugin
3. Disable caching for the “web hook” or “IPN URL” used by your gateway.
If the gateway you chose has a web hook or IPN URL, it will be shown at the bottom of the PMPro Payment Settings page. Make sure this URL is not cached by your system. Some hosts (especially shared hosting setups) may have additional caching of this URL only for IP addresses that hit the URL often (i.e. the gateways, but not when you navigate to the URL yourself). So it may not appear cached to you but will be cached when the gateway hits it causing problems. Your gateway will typically show these errors to you and you may be able to get it fixed by opening a support ticket with your host and explaining the situation.
which setting do i disable in w3 totoal cache?
