[support] comment.tpl.php $links not available

[Benjamin Jacob]

Hi All,

Am using drupal 6. Don't know what went missing where but I can't see the reply/delete links in my comments on the node pages. 
I am certain I had these links available at some point of time. Not sure what things have changed during the past few months.
I did a dprint_r of $links in comment.tpl.php but it shows me absolutely nothing.

How and what and where do I check for this?

cheers
