@pichalite Works perfectly! I got my Subcategories back - thanks so much for your help!

Hello everyone,

I modified the Persona Theme so that Subcategories are shown on the Mainpage and not only on the Category-Page. That worked well so far in 0.8.3; I just modified the templates/categories.tpl by adding basically this:

[...]
<!-- BEGIN categories -->
<!-- IMPORT partials/categories/item.tpl -->
<!-- IF categories.children.length -->
<!-- BEGIN children -->
// HTML Representation of a Subcategory
<!-- END children -->
<!-- ENDIF categories.children.length -->
<!-- END categories -->
[...]

That gave me a Overview like this:

After upgrading to 0.9.3, I dont get this to work anymore. If I use my old code above, NodeBB logs following Stacktrace:

error: RangeError: Maximum call stack size exceeded

and restarts everytime he tries to load the theme, so nodebb is only working if I switch themes. I'm running NodeJs 4.2.3 (with 0.10 it didnt work either and the error was undefined undefined).

I played around a bit and found out that it dies when I try to call <!-- BEGIN children -->. I also tried to call <!-- BEGIN categories.children --> (wont work) and tried to move the inclusion to templates/partials/categories/item.tpl as

<!-- IF ../children -->
<!-- BEGIN children -->

<!-- END children -->
<!-- ENDIF ../children -->

This gives me the same Exception with a slightly different stacktrace

Has anyone an idea why this isn't working anymore/where my mistake is? What is causing this error? I would really like my subcategories back at my mainpage.

Thanks for your help!
