Have you ever tried to make a post in WordPress, Xenforo, or some other content management system only to get a 500 internal server error?
I was chatting on Skype yesterday with one of my friends (and Name Hero customers) who was having this issue over and over.
First off, I can relate as I’ve experienced this for nearly a decade now, and always wanted to pull my hair out troubleshooting the issue.
You need to disable Mod Security
After spending HOURS troubleshooting this many years ago, I discovered it was Mod Security blocking it.
More specifically, some word processing programs such as Microsoft Word insert ambiguous characters into your text which when pasted into WordPress (or similar) can create the error as Mod Security considers it a threat.
This is also the same problem many face when trying to get the Manage WP Worker plugin to connect.
How to disable Mod Security
You can then disable it for the domain in question or for your entire cPanel account:
If you administer your server (i.e. on a VPS) you can login to Web Host Manager -> ModSecurity Tools and you can disable the one rule causing the issue (if you don’t want to disable Mod Security all together).
This works as well, but sometimes you’ll find there are multiple rules creating the issue. In a lot of cases it’s just as easy to disable it all together.
How to keep your website secure
Mod Security acts as a web application firewall blocking your site from many hacking / exploit attempts. If you decide to disable it you need to make SURE you regularly change your passwords (using strong ones) as well as keep your software updated.
This means regularly updating WordPress (when updates are available) as well as all your plugins, themes, etc. Running older versions of software is the number one reason websites get hacked. Also using insecure passwords without strong characters!
