audioatwork.com critical error (E_COMPILE_ERROR)

Hi there,

We have a situation. Our website crashed and is giving an error. The WP login is giving the same error but i am able to login in recovery mode. The WP 24h e-mail says this:

Foutdetails
===========
Een fout van het type E_COMPILE_ERROR werd veroorzaakt op regelnummer 313 van het bestand /customers/d/e/e/audioatwork.com/httpd.www/wp-content/themes/enfold/functions-enfold.php. Foutmelding: Unparenthesized a ? b : c ? d : e is not supported. Use either (a ? b : c) ? d : e or a ? b : (c ? d : e)

Anyone that can help us??? It’s been down for a couple days, and we really don’t know how to fix this.

Thanks!
