After reboot RPI no changes are saved?
- 
 Hi all. 
 I got a strange issue.
 When i reboot (Sudo reboot) the RPI after changes in the config.js and saved the config file it gets back to the same status that i hade befor changes was made.
 Like if i delete a module from the config and save tha file it works fine but if i do a sudo reboot after this it is back to latest version and the module are back ?Aslo i got som issues with the MM freezes and nothing can be done just power off the RPI and restart it all. I dont run the latest MM 2.1.1 as i got problems updating. 
 Is the best way to re install the full MM or is it a solution to this?Well hope that i can get some help if some one have hade the same kind of issue and solved it.

 @wizz I have the same problema. When sudo reboot my config.txt is lost. I have to edit it everytime I shutdown too.

 @wizz 
 Have you found a solution?I have the same problem now. 
- 
 @Blackmirror i would try sudo shutdown now -r (r=reboot) I have worried about sudo reboot not saving files, but it has never happened to me… (on 8 different systems with MM running) 
- 
 I am having this problem of any config changes do not stay after reboot. 
 I am editing config.js and custom.css like I have for the last year or so.
 Any work around?

 Having the same issue, if I “sudo reboot” or “sudo shutdown now -r” I loose the changes in my config.js and my custom.css they will not save for some reason. Problem JUST started Monday. 
 Anyone have a solution?
