Why is the Sidebar Collapse missing on my site?

[darkpixlz]

Hello,
On Meta and the rest of Discourse sites with the sidebar enabled there’s a collapse button.

However on my site this button is missing

(The same goes for the default theme, I dont want to change my theme)

Any idea on why this is?

You’ve tried safe mode?

There is likely some css in your theme that’s hiding it.

Never mind, something’s definitely hiding it, probably a component. I’ll look into it.

@darkpixlz This issue seems to have been from the header search component. Thanks to @nolo for identifying the component causing the issue, I’ve just pushed out a fix.
