Update: I just did an update to Wordfence, meaning I again had to manually comment out this code again. Great time to test if the problem persists: it does. [Ugh!]
I am on HostGator, and it tells me my current version of PHP is now 5.4.29. Yet I have to comment out the part to run authActionNew to make AffiliateRoyale to work. Meaning, even though I have a PHP version greater than 5.4.0, authActionOld runs better for me.
Could the need to choose the PHP version be unnecessary? Could there be something wrong with authActionNew?
