SOLVED: PDF preview not working

Greetings,

After copying our current environment to a new server PDF-previews suddenly aren;t working anymore. I can download the PDF’s and they look OK, but the preview pane stays empty (apart from the no preview available message which I sometimes get.) Copy is made with an rsync (just tweaked the config.inc to reflect things like the new files_dir location)

Running OJS version 2.4.8.0.

Going from Ubuntu 10.04.4 LTS to debian 8 (jessie)

Is there something I need to install on the new server?

Any help would be apprciated.
Regards,
Willem.

Ah, solved.

Apparently the Google PDF viewer plugin was installed and it didn’t have the proper authentication. It’s disabled now and we can work fine now.

Regards,
Willem.
