Here is my fix:

On lines:
67,121,169,229

change:
($options, &$cache, 0, &$total);

to:
($options, $cache, 0, $total);

That is just remove the & in front of the $, seems to be working fine.

OK, I found the solution. Instead of trying to call the function directly I can just use the WP do_shortcode() function:

echo do_shortcode('[associated-posts]');

This works great in my theme file. Thanks for the great plugin, keep it up.
