What are you trying to change the chmod permissions to?
And also what files are you trying to chmod for these?
CHMOD the following files to 666 (ie, make sure that PHP can write to them).
./inc/settings.php
./inc/config.php (you must rename config.default.php to config.php first)
./inc/languages/*your_language*/*all files* (optional)
./inc/languages/*your_language*/admin/*all files* (optional)
CHMOD the following folders to 777 (ie, make sure that PHP can write to and execute from them).
./cache/
./cache/themes/
./uploads/
./uploads/avatars/
./admin/backups/ (optional)
I did all that but it like not saving
It seems to be something to do with your host instead of myBB. In which case, anyone here would not be able to help. You should contact GoDaddy about your problems because it seems to be from a host end, not myBB.
