[Mobile WMS](https://hub.acctivate.com/articles/troubleshoot?hsLang=en#mobile-wms) April 14, 2025 # What to do if localhost/accthandheld is blank ## Enable HTTP Errors by opening “Turn Windows features on or off” on the Server, then browse to Internet Information Services > World Wide Web Services > Common HTTP Features and check the box next to HTTP Errors. The first step in troubleshooting any connection issues with Acctivate Mobile and/or IIS is to review the error code that you receive when attempting to browse to http://localhost/accthandheld from the server where Acctivate Mobile is installed. Usually, those error codes are very informational and can point you in a direction to get things resolved. This article covers the solution when the localhost/accthandheld page is completely blank and shows no error code (see screenshot below). ![7-28-2016 3-40-04 PM](https://help.acctivate.com/wp-content/uploads/7-28-2016-3-40-04-PM-1.png) This is caused by a Windows Feature called HTTP Errors not being enabled. To enable this feature, open “Turn Windows features on or off” on the Server, then browse to Internet Information Services > World Wide Web Services > Common HTTP Features and check the box next to HTTP Errors. ![7-28-2016 3-45-59 PM](https://help.acctivate.com/wp-content/uploads/7-28-2016-3-45-59-PM.png) Once that feature is enabled, Windows may prompt you to reboot the server. After the reboot, try to reach http://localhost/accthandheld again and you should see a detailed error stating what the issue is. ![7-28-2016 3-47-30 PM](https://help.acctivate.com/wp-content/uploads/7-28-2016-3-47-30-PM.png) -
