ModSecurity is a web application firewall. It checks the requests coming into your website and blocks common attacks, such as attempts to inject malicious code. It’s switched on for your domains by default.
When it might get in the way
Very occasionally, ModSecurity can mistake a genuine action for an attack – for example saving certain content in your website’s admin area, or a form that won’t submit. If this happens, turning it off briefly can confirm whether it’s the cause.
Turn ModSecurity on or off
- Select Websites in the left side bar, then select the website you want to manage.
- Select Security in the menu along the top, then ModSecurity in the menu on the left (or scroll down).
- ModSecurity is set per domain. Use the switch next to the domain you want to change.
