Hi @rumyan,

Welcome to WordPress Trac! Thanks for the ticket.

I'm facing the same issue in WordPress 5.4-RC3-47470 version. Check attached screenshot for error.

JS error

Hi @rumyan, and welcome to WordPress Trac!

I'm unable to replicate this issue in a new installation of trunk. Does it still happen when using a default theme with all plugins disabled? If so, can you please provide steps to replicate it?

@dlh Replicated the same issue in version 5.4-RC3-47477.

Add backslash in Site Title like attached screenshot.

Thanks @mukesh27. I misunderstood and thought this was an issue when adding a backslash in the Customizer, but now I see that the issue happens when loading the Customizer.

At a glance, this issue is a side-effect of [46389]. It also seems to happen only when the backslash is the last character in the site title such that it escapes the closing quote in the Underscore template.

If backslash placed at the end of the title, it cause an error, I set site name something like Test / New, the Customizer works fine.

Exactly. If the last character in the page name is "\" then no options work in the customizer.
The error still occurs. I have checked in a working website and in a new installation.
