It may happen that the WebUi window or the code view are not displayed in control. It may appear black or only as a gray background area.


Error Message

In most cases this will not print an error message inside PIXERA, or in the Control log.


Symptoms

The Webui cannot be displayed. The code view of actions cannot be displayed either.


Cause

This happens when the Control web server cannot connect or start. There can be various reasons for this, the most common being that the set adapter or port is not available.


Solution

Check in the settings whether the Control adapter you have set up actually exists. It is possible that this address has changed, preventing the web server from starting. Please set it to an existing adapter and restart PIXERA.
