rb800

Good morning, I have a rb800 and a while he began to experience problems withwebproxy, spontaneously stops working, you lose all the configuration that was loaded,watching from the winbox to enter the ip-WinProxy option appears all in white and without any configuration.
In the log I could see that an error that says error webproxy-stat / var / store …

Also with the same drawback last time I had to re-build a backup of the configurationbecause rebooting is not restored.

I need to know what caused this problem. Thank you.
