Site security changes (ConoHa)

Change settings

Follow these steps to change your site security settings.

This will display the ConoHa control panel page.

Navigate to ‘Site Administration’ → ‘Site Security’ → ‘WAF’ tab.

From the displayed list of blocked attacks, look for the log recorded when you tried to add the script to the widget.

The attack was a ‘cross-site scripting attack.’ Please verify the time and IP address.

Once you have identified the log you want to exclude, click the ‘Exclude’ button.
