If you recently auto upgrade your WordPress website, it is possible that you are not able to visit your.
Chances are, you ran into an issue caused by a builtin module – WP-SpamShield: https://wordpress.org/support/topic/auto-updated-and-broke-many-sites/.
Steps to debug this (Linux/Unix + httpd2):
1. Check your system log: /var/logs/apache2/error.log. You may found some logs like:
[Wed Feb 01 06:14:38.412431 2017] [:error] [pid 14390:tid 140592994543360] [client 91.220.131.134:60744] FastCGI: server "/usr/lib/cgi-bin/php5.fcgi" stderr: PHP message: PHP Fatal error: Class 'WPSS_Utils' not found in /path_to_wordpress/wp-content/plugins/wp-spamshield/wp-spamshield.php on line 7323, referer: http://coderstan.com/wp-login.php
2.If so, the solution is to deactivate this module manually. Find the plugin at following path:
/path_to_your_wordpress/wp-content/plugins/wp-spamshield
3.Run this command:
mv wp-spamshield/ wp-spamshield_inactivate/
That will force inactivation of this plugin and you could change the name back after you update this plugin to a stable version.
That’s it.
