Just temporarily change it to this:
Code:
global $mv_hide_link, $vbulletin;
//if ($mv_hide_link)
{
$vbulletin->templatecache['polloptions_table'] = str_replace('<a class="textcontrol"', '<a style="display: none;"', $vbulletin->templatecache['polloptions_table']);
}
Don't leave it like that though.
Let me know if it "works" like that... This will let me know for sure if it's the logic that is failing or the template edit that is failing.
