Is this plugin still actively developed?
Glad to see a wordpress plugin that uses TCPDF and supports UTF-8, bidirectional text, etc.
Unfortunately, it seems to be b0rked for 3.0.4. Not output is generated after clicking on the AS-PDF link. Something must be happening as the browser returns this URI: http://opensiddur.org/wp-content/plugins/as-pdf/generate.php?post=2520
...but there's no PDF to download (forced or not).
