Parse error and can't edit page content with enfold

I have updated to the latest enfold theme 3.6.1 and I can’t get to my page content to edit at all. Getting parse error Parse error: syntax error, unexpected ‘:’ in /home/_/public_html/skin/404.php on line 2

Prior to the update, when I selected “edit page” the page editor would come up, but the area where page content is to be shown and modified, remained white showing no content.

I need to modify the site info ASAP and desperate to find help on this.
Thank you
Michael
