So I tried updating all of the core files, still no luck. I'm wondering just where the issue could be, as this doesn't even make sense! I checked out vote.php and found this like towards the header:
PHP Code:
if ($current_user->user_id == 0 && !anonymous_vote) {
error($main_smarty->get_config_vars('PLIGG_Visual_Vote_NoAnon'));
}
I can't figure out where to find get_config_vars, or what value PLIGG_Visual_Vote_NoAnon has but I'm almost positive this is the block of code that's messing up my redirects.
