Edit Server Settings - Error

[peterstannard]

When i go into Server Settings in the Admin Panel i get the following error;

Failed to make backup of Settings.php - make sure Settings_bak.php exists and is writable.

What should i do?

check if you have the file settings_bak.php in your forum folder if you have it chmod it to 777

if you do not have it make a copy of settings.php, rename it to settings_bak.php and make it writetable.

rename it to Settings_bak.php and made it 777 and it worked fine.

thanks
