After the Meteor update to 0.8.0 I had some issues with iron-router, but I was able to fix them by adding the blade-layout package and updating iron-router...

However, now I get the following error in the browser console, (the normal console doesn't throw out any errors, just tells me app is running at localhost:3000).

This is the error I get in the browser console when I try to visit the home page. This only started happening after I updated to Meteor 0.8.0

Sorted by: Reset to default 10

you have a line there which says where is the error

 at Template.__define__.HTML.DIV.class (http://localhost:3000/client/html/template.page_layout.js?b9f71b600d93464d684baf69d25d5f1c78c77785:6:22)

You should use the blaze-layout and change the yield tags inside of a layout template

the old way {{yield}} or {{yield 'footer'}}

a new way {{> yield}} {{> yield region="footer"}}

https://github./EventedMind/blaze-layout

Alternative cause

Template

<template name="answer">
        <li class="answer-title">
            {{answer .. this}}
        </li>   
</template>

When answer is not a helper function the error Can't call non-function is thrown, becaue this syntax is only for calling helpers and passing them parameters. Ie. When answers is:

Templates.answer.helpers({
   answer: function (parentCtx, self) { return self.batman ^ !parentCtx; }
});
