ZM_WEB_XFRAME_WARN
When creating a Web Site monitor, if the target web site has X-Frame-Options set to sameorigin in the header, the site will not display in ZoneMinder. This is a design feature in most modern browsers. When this condition occurs, ZoneMinder will write a warning to the log file. To get around this, one can install a browser plugin or extension to ignore X-Frame headers, and then the page will display properly. Once the plugin or extension has ben installed, the end user may choose to turn this warning off.
