Does anyone know how to disable the breadcrumbs on the front page only?

What app is on your front page?

Forums.
(I think.  That's what you're asking right?  Like is it forums, commerce, pages etc?)

Put this in custom.css

[data-pagemodule="forums"][data-pagecontroller="index"] .ipsBreadcrumb {
 display:none; 
}

 

I just tried it, it didn't work.
But thank you very much for the effort none the less.

EDIT: After a little reading it looks like a tag is missing from before the square brackets.
Not sure what tag I should use exactly.

It works on my site. Whats the URL ot yours?

huh, I wonder if some other bit of our custom .css is interfering with it?
