We have a number of WordPress installations on a cPanel server and most of the time, we get notifications when one of them is down. However, the newest site on the server has gone down a few times and we haven’t gotten notified.
A few notifications do come through, so far when there’s a Socket timeout. But when we get an error like the following, nothing is sent.
Parse error: syntax error, unexpected ‘/public’ in /home/clientname/public_html/wp-includes/taxonomy.php on line 4851
The above error in a plugin file caused the site to go down. We didn’t know until the client called us about it. Are there any settings we should be aware of in WordPress to make sure site down notifications are being sent correctly? Are there any plugins that may interfere with icinga’s processes, such as firewalls?
