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. ## Related - [Blueprint Administrator Error (141254): "The Model Manager is currently unavailable.
