You can set the fping path for each slave in your config.
For example, you might have something like:

*** Slaves ***

+slave1
display_name=...
++override
Probes.FPing.binary = /usr/bin/fping

See http://oss.oetiker.ch/smokeping/doc/smokeping_master_slave.en.html

If I understand this question correctly, then I think you are looking
for the 'nomasterpoll' option.

See http://oss.oetiker.ch/smokeping/doc/smokeping_config.en.html
(search the page for 'nomasterpoll')

The most common problem here is that the user your webserver runs as
does not have permission to update the RRD files.
So you should check the ownership and permission of these files.

hope this helps,
