In our forums, the title tag is displayed as the complete breadcrumb, as the following example from the source code shows: Post title > Category > Forum title.

(Example excerpt from the source code: "<title>Why do school lessons start so early in the morning: Sense or nonsense? 'What annoys me about school 'Swiss Community | netz-familie.ch</title>"

However, I only want the post title to appear in the title tag, as otherwise the title tag becomes far too long for SEO. How can I change this?

Thanks and best regards,
Steven
