Thread:Extension talk:PageAttachment/Warning: Unexpected character in input: '\' (ASCII=92) state=1

Thank you for writing this extension! When installing this, I'm seeing (in the browser when trying to access a page): Warning: Unexpected character in input: '\' (ASCII=92) state=1 in extensions/PageAttachment/SetupExtension.php on line 131 Parse error: syntax error, unexpected T_STRING in extensions/PageAttachment/SetupExtension.php on line 131

Line 131 in SetupExtension.php says: $requestHandler = new PageAttachment\RequestHandler;
