Admin Level - Webmaster

Certain editing actions can cause problems for your users, so the CMS will display a red warning button at the top of the Website Design page. Click the button to review the warnings.
Page Warnings

Items with a red warning sign are critical and cannot be ignored.

Items with a yellow warning sign are potential issues. If you intentionally performed an action that resulted in a warning, click Ignore to dismiss it. For example, perhaps you set the admin level of a page to Webmaster because you do not want anyone below the level to access the page. Once you click Ignore, it will grey out the warning. You can still click Resolve if desired.

Click Resolve by any warning to have it automatically fix the issue. Once you do this, it will let you know what it did to fix the issue, and it will disappear in three days.
