I (stupidly) made a few changes on the parent functions file for my child theme and the website has crashed. I was remotely accessing the dashboard but I can't seem to access anything now at all even the login. I haven't touched anything via FTP.
This is the message I keep getting:
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request. This is the site http://www.citizensuk.org
I don't know how to repair this at all and I can't access the functions file to restore it to normal.
Please help me!
