Yes it has - quite nicely for years. The upgrade to 6.12.2 and then 6.12.3 caused the issue. I reverted to a 6.11 zip and all is working again. From the log file - problems and errors with the dark-theme, nginx and a couple of depreciated plugins. I'm going to stay at 6.11 for a while, as I see other comments that 6.12.x is causing other major problems. Might just be me - but after years of clicking OS update and installing - I'm a little mouse shy now. Thanks for your help !!!! Cheers.
Dashboard is not on the top - it is on the left but just text. Mouse will click and activate this text to go to the different pages, but mouse will not activate any other buttons or icons. Cannot upgrade, start the array, etc. Has anyone else had this happen?
