Hello all need some help as I have no idea how to fix this problem as I can not even disable the cache in BO so I can make any upgrade. I contacting my hosting provider and they chnged the 777 and 666 to 755 and 644 but as soon as I try to turn off cache it goes all back to 777 and 666 I cant even upgrade a module as I get errors like this '' Exception thrown by module on upgrade. Cannot extract module in/public_html/app/cache/prod/sandbox/5ade16192561a/ to get its name.'' I have no idea what to do any help out there I will appreciate it below is my server information
