The default adminstrator account is configured with:

username   admin
password   admin

On a Linux installation, BrowserCRM should have write permissions to the entire /browsercrm directory.

Particularly, it must be able to write to the /data directory and the sub directories.

/data
/data/mail
/data/files

For example:

Notice: Undefined index: order in C:\www\vhosts\localhost\crm\webmat\webmat_database_table.inc on line 1352
Notice: Undefined variable: items in C:\www\vhosts\localhost\crm\webmat\webmat_database_table.inc on line 840

This occurs when the PHP error_reporting setting includes E_NOTICE. BrowserCRM will generate unwanted notices and subsequent errors at this level of error_reporting and will not run correctly.

See Configure PHP for details of changing your PHP configuration.
