Hello Gypskying,

I highly recommend you dont use v8.1 either it has no security, I recomend using 7.6 from RavenPhpScripts plus they have over 10,000 fixes that includes loads of security too !

Although, I am not your father so you can find the fix located below....

///NO RIGHT SIDE BLOCKS FIX///

Open up the theme.php of the theme you wish to fix. OPEN AND FIND:
Code:

if ($index == 1) {

REPLACE WITH

Code:

if (defined('INDEX_FILE')) {

This should fix your issue.
