## **1. Check your deployment**

This issue is typically caused by wrong configuration/deployment of charts.

First, please check to make sure the proper VitaraCharts plugin is deployed; In the case of mobile, the plugin to download is called VitaraChartsMobile.zip

Follow all the installation steps listed in the [install guide for mobile](https://docs.vitaracharts.com/install-docs/installing-on-microstrategy-mobile).

**Note** that after deploying, the plugins folder will have several Vitara related folders (one for each type of chart)

* In case a cluster of mobile servers are being used, it is critical to ensure Vitaracharts is deployed to all nodes in the cluster.
* Also please verify that the version of Charts deployed in Mobile and Web both are same.
* If you are using VitaraCharts for Documents please make sure that Display widget option in (iPhone, iPad,Android..etc) is enabled for the widget. \</br>

You deployed charts correctly and still you are seeing a blank screen on mobile/library application in IOS or android device, please delete the chache of the application and reload the dossier/document.
