How to uncomment?

i would like to know that too. where did u read/hear it?

A commented line in php
<?php //comments_popup_script(); // off by default ?>
An uncommented line
<?php comments_popup_script(); // off by default ?>
The // says “ignore whats next”, so taking that out means it won’t be ignored. If that makes sense…

For a thorough and technical explination of comments you may see the PHP manual:
https://php.net/manual/en/language.basic-syntax.comments.php

Cool, thanks guys.

thanks from me too… i thought uncomment was something like misunderstanding…
