I just had a referral sale from an affiliate on March 31st, however, the plugin didn't register any commission to that affiliate or count it as a sale.
I know this was a good referral because the affiliate ID was on the Paypal receipt and I also checked the affiliate referral link and it was good. For some reason, the Affiliate plugin is registering lots of click-throughs but no sales/commission data.
I tried the following to solve the issue:
*I did a test payment with my own Paypal account and it worked. The plugin successfully tracked it as a click-through, a sale, and awarded me commission. This is strange, because if it worked for me, I think it should work for everyone else.
*I tried the eStore_post_payment_debug.log option, but when I go to the log file...it is blank.
*I noticed for a sale I just had today that the ipn_handle_debug.log file showed "SUCCESS :No Referrer Found. This is not an affiliate sale" So, it looks as though it is checking for an affiliate referral. I don't know how to go back and check the log file for the referral sale I had on March 31st though.
Thank you for your attention to this and for your amazing plugin!
