You should try use: ProxyErrorOverride off
If you had something like this:
ProxyPassMatch “^/(.*\.php(/.*)?)$” “unix:/var/run/php-fpm/php.sock|fcgi://localhost/some/path” enablereuse=on
Advice is to change to SetHandler:
<Directory "/some/path"> <FilesMatch \.php$> ProxyErrorOverride on SetHandler "proxy:unix:/path/to/sock/php.sock|fcgi://localhost" </FilesMatch> </Directory>
