PHP Code:

<if condition="(THIS_SCRIPT == showthread) OR (THIS_SCRIPT == showpost) OR (THIS_SCRIPT == printthread)">
<link rel="canonical" href="$vboptions[bburl]/showthread.php?t=$threadinfo[threadid]<if condition="$pagenumber>1">&page=$pagenumber</if>" />
</if>
<if condition="THIS_SCRIPT == index">
<link rel="canonical" href="$vboptions[bburl]" />
</if> 


Is wrong.
Specifically:

PHP Code:

"$pagenumber>1">&page=$pagenumber</if>" /> 


Typo, or real code? I'm dubious...

I used this fix:

PHP Code:

<link rel="canonical" href="$vboptions[bburl]/showthread.php?t=$threadinfo[threadid]<if condition="$pagenumber">&page=$pagenumber</if> 


That works on my board.
