Disabling plugin locked me out

I was disabling plugins to try to locate a conflict, and am now getting this error in the backend:

Fatal error: Unknown: Failed opening required ‘/data/15/4/26/72/4026072/user/4471383/htdocs/home/wordfence-waf.php’ (include_path=’.:/usr/share/php:/usr/services/vux/lib/php’) in Unknown on line 0
