Any time you encounter a problem like this with WordPress step one should always be to review your error logs. If you’re using Apache on Ubuntu this would be in /var/log/apache2/error.log. Blank pages provide no information to use to start troubleshooting but in most cases your log files would.

If this happened suddenly and you do not see any obvious indication of an issue in the log files I would check if any plugins or themes were recently update in these WordPress installations possibly causing a conflict between plugins.
