Error says line 657 and 680
but what you have to fix is on lines 652 and 675
Burt above gave the fix here it is in full so you can just cut and paste into those lines:
'<img src="%1$ssupport-forum-%2$s.png" alt="[%3$s]" title="[%3$s]" style="vertical-align:top; margin-right:0.3em; width:14px; height:14px; border-width:0;" />%4$s',
Same code goes in both lines.
THANKS to Burt for providing the fix!!!
