Website is down, How to fix it?

I was updating plugins, themes etc for http://www.emilylouisesinging.com then this error came up:

Parse error: syntax error, unexpected T_STATIC, expecting ')' in /home3/paceprom/public_html/emilylouisesinging.com/wp-content/plugins/testimonials-widget/lib/aihrus/class-aihrus-common.php on line 88

It would seen that the Testimonial Widget is causing the problem and my first thought is to just get rid of the widget (not being used anyway) but I cant get past the "Parse error" that I pasted above. It even shows up when trying to view the website
