# Blueprint Error: "The Model Manager is currently unavailable. Please try again shortly".

### **Problem**:

When I select Devices from the Assets section or when I attempt to close a period I receive one of the following errors: "The Model Manager is currently unavailable. Please try again shortly" "The period end settings could not be read" The Blueprint Administrator log file shows a an message code of "**MessageCode: 141254**"

How can I correct this problem?

### **Resolution**:

The symptoms are caused by a malformed 'C:\Program

Files\PharosBlueprint\SettingsCache\ServerSettings.xml' cache. To fix the problem please see the steps below for the version of Blueprint Enterprise you have installed.

### **For Blueprint 3.5**

1. Stop the TaskMaster service.
2. Delete the file 'C:\Program Files\PharosBlueprint\SettingsCache\ServerSettings.xml' (it will be automatically re-created correctly).
3. Start the TaskMaster service.

### **Blueprint 4.2 through 5.2**

1. Stop the service "Pharos Systems TaskMaster".
2. Open the directory "C:\ProgramData\PharosSystems\Blueprint\SettingsCache" and create a new folder called "old".
3. Copy the two files named below in the directory in step 2 to the Old directory you created above.

***ServerLastKnownGood.xml***

***ServerSettings.xml***
4. Delete these two files.
5. Start the service "Pharos Systems TaskMaster".

*The files will be re-created once the service is started.
