Assuming that $msg is a Crawler object which contains this html

<div class="mola_wrap"> 
    <span class="mola" title="titleinside">109</span>
</div>

your code is just fine, maybe the website you are crawling does not have .mola class in some pages

gist.github.com/kaseOga/92d68e7f3216a2f50e32 here is all the html (i get these doing an echo $msg->html();)

Hmmm Over a year ago

can you try doing $mola = new Crawler($msg->html()); and then call $mola->filter('.mola')->text();

I'm VERY retard cause i had the same problem with other filter before this with same $msg and the problem is $msg is a Crawler of a bucle, some post can have span.mola and other post can't have... the solution is simple adding a if counting if exist o no :P sorry and thanks!!
