[Plugin: AS-PDF] No PDF output

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: https://opensiddur.org/wp-content/plugins/as-pdf/generate.php?post=2520

…but there’s no PDF to download (forced or not).
