Evening Archers

O am trying to find where KDE Plasma  stores the settings for multiple monitors
 but can not find it yet  .

I have 2 identical monitors both were working fine  now i have lost the panel
on the one monitor and can not restore it i have tried all the suggestions i
can find so last resort i want to look at the configs for the monitors  so
which file are the configs stored in please . 

Thanks   Pete
