squirrel mail help please
 

Preference file, ../data/krayzie.pref.tmp, could not be written. Contact your system administrator to resolve this issue.

when i try to login

A permissions error, it seems.

Under what user and group is the webserver that is hosting this "SquirrelMail" running?
What are the permissions of the 'data' folder?
The webserver user needs write access for that folder.

the folder is 777

In which case I have no idea.
Does that file already exist? If it does, delete it. That's all I can think of...

the .pref file is 644 so i dunno if it is supposed 2 b 777

As long as the webserver user can write to it.
What user is the websever running under?
Who's the owner of the .pref file?

I'd say deleting the .pref file might work though.
