Fallback to export server disabled

This happens when the offline export module encounters a chart that it can't export successfully, and the fallback to the online export server is disabled. The offline exporting module will fail for certain browsers, and certain features (e.g. exporting.allowHTML ), depending on the type of image exporting to. For a compatibility overview, see Client Side Export.

For very complex charts, it's possible that exporting fail in browsers that don't support Blob objects, due to data URL length limits. It's always recommended to define the exporting.error callback when disabling the fallback, so that details can be provided to the end-user if offline export isn't working for them.
