Lost my Solution
I went into the threat management solution and added some applications. After I saved and closed, it disappeared from the Solutions dropdown. And, when i go into the apps I added, it doesn't show as part of the solution. Any idea what happened to it?
Have you reapplied your license via the Archer Control Panel before you made changes to the solution? If so, there might be a license issue and the solution was hidden.
Just an FYI, 6.4 reaches it end of support this month.
