Well if you set correct permission (chmod 777) and continue receiving this
error then you have a problem with PHP server configuration. It's not an error
of vCard Lite. Sorry!
I tested vCard Lite in NEXEN.net (trial) and Datablocks.net (free) and receive this
error from them.
But in a paid web hosting I didn't receive this error. Hmmm I suspect that the
problem is from them because "it's free" and don't allow use all feature of PHP.
Example:
Nexen.net disable mail function in trial test.
The copy function is really powerful command soo it's no surprise that it's disabled.
The "SAFE MODE" it's enabled by system administrator.
In your admin center see "PHP Info" and looking for "safe_mode". It's "ON"
ISP useally set in PHP configuration (SAFE MODE) to NOT allow
function which could possibly be a security risk.
Soo you will need DISABLE this feature from your config.inc file.
