Hello. I try to se Earning by visits,

but when i set “I have my own visit counter (callback)” and put:

ppc_pvc_views
or
ppc_wp_slimstat_views

it write me error message: The specified visits callback returned NULL for a random post – are you sure it is correct?

But, i have both plugins installed, activated and for sure, cache deleted.

I try to wait some days, but not helps me.
