aitbreviews, in case you haven’t solved the issue I have corrected mine. All I had to do was manually update wordpress after disabling all of my plugins. Once updated I enabled all the plugins and everything is working fine now.
Also getting the same password hash error. Site worked perfectly fine last week. Now all of a sudden it doesn’t work. WordPress codex is of no help.
Fatal error: Class ‘PasswordHash’ not found in /home/cssacila/public_html/store/wp-includes/pluggable.php on line 2138
