Hey,
I have a problem uploading pdf-files to events. Have a look at the file Test.pdf here:
http://gapid.de/akademie/veranstaltungen/event/0/17-weiterbildung/197-integrative-schmerztherapie-in-der-anthroposophischen-medizin-berlin
The file can't be displayed. The console in the developer Tools says "Error: Invalid or corrupted PDF file". However, the file is ok before I upload it (it's the one attached to this message). I tried this with several different pdf files. So, the problem seems to be due to Matukio.
Thanks!
David
