I get this error: "SyntaxError: Invalid regular expression: /^/[/: Unterminated character class (form not submitted) on any of the latest browser (IE, Chrome, Mozilla, Opera) versions. This happens when I attempt to save configuration changes to any build.

If I went to Dev settings and change document/agent settings to IE 8, then I can save but I can't navigate the buttons to add configurations (for example: build steps).
