PKP PLN Plugin Fatal Error

Continuing the discussion from Registration on LOCKSS with PKP PLN Plugin:

Dear All,

I have similar problem with Plugin. At initial stage, as I activate the plugin, the journal’s system blocks itself with this warning message.
I will be very happy if you could give me an advise too.

Best Regards

Fatal error: require_once() [function.require]: Failed opening required ‘Archive/Tar.php’ (include_path=’.:/home/’) in /home/ on line 32
