VBSEO code in "Posting Permissions"

Hi, I have vBSEO 3.1.0. After I upgraded my forum to 4.0.2 everything works fine, except there is chunk of code in the "Posting Permissions" box. Here is the code :

HTML Code:

" . construct_phrase("$vbphrase[vbseo_trackback_is_x]",  "misc.".VBSEO_VB_EXT."?do=linkbacks#trackbacks", "Off") . " " . construct_phrase("$vbphrase[vbseo_pingback_is_x]",  "misc.".VBSEO_VB_EXT."?do=linkbacks#pingbacks", "Off") . " " . construct_phrase("$vbphrase[vbseo_refback_is_x]",  "misc.".VBSEO_VB_EXT."?do=linkbacks#refbacks", "Off") . "

Please let me know how to fix it.

vbseo 3.1 is NOT compatible with vb4. You must upgrade to vbseo 3.5 RC2.
