Unspecified error when replying, missing editor icons

[Mouth]

I have the following issue on my site that recently arose, and after diagnosis and turning off Add-Ons etc. I am unable to resolve it and would like some help or pointers please.

When at the thread quick reply and click the 'More' button, an 'Unspecified Error' occurs at the top. If I click the 'Reply' (eg. [...]/reply?quote=2476696 ) on a message, the editor is missing the toolbar.

I believe it's related to missing or error in javascript, but cannot locate the issue. Help or pointers appreciated. Thanks.

Anything show up in the server error log?

Anything show up in the server error log?

No, unfortunately not. One of the reasons why I'm thinking JS issue rather than XF or Add-on?

I can try to debug it if you give me FTP and admin access.

Thank-you to Jake for diagnosing my issue, much appreciated.
