By default, FooConvert is not compatible with inline scripts. Inline scripts are often discouraged in WordPress as they can pose a security risk. As such, you are unable to embed certain items within a FooConvert widget.
However, this can prevent you from using certain elements in your widgets, such as forms. To combat this, FooConvert allows you to enable compatibility and allow for inline scripts. This setting needs to be manually turned on for each widget in which you want to allow inline scripts, to limit potential security risks. We recommend only allowing this for trusted sources.
To enable Compatibility, go the the general settings for the widget. Compatibility is set to Disabled by default; click on this and then select ‘Allow inline scripts’.
