I was getting errors with the Support Forum plugin when a post was sticky or closed.

The issue was with the sprintf statements in support-forum.php lines 652 and 675.

Basically each placeholder for the sprintf statement was written wrong. Was:

$1%s … $2%s … $3%s … $3%s … $4%s

Should be:

%1$s … %2$s … %3$s … %3$s … %4$s

I never found this error. I should check it out.
