Hi Mahdi,

Something else to expose here is the distro you're using.  The logo in the dashboard screencap is extremely outdated and customized, which would tell us you're running a very old distro.  Can I suggest working with a more recent distro [1] or working with a consulting company[2] to give you a hand?

Thank you,

Jimmy McArthur
