I have downloaded squirrelMail from SquirrelMail Official Website, then I uploaded the extracted files to a free hosting account on x10hosting.com.
when I try to connected to the Squirrel Mail, I get the following error
Error opening ../data/default_pref Could not create initial preference file! /data/ should be writable by user sikas Please contact your system administrator and report this error.
I want to know how to solve this issue and what files exactly should be edited.
PS: I edited the config file but I`m not sure about the values I entered.
