Can you run "the command" on your server and check the logs?
What OS do you have on your server?

Hi, Maxim,

I can upload ppt files now. However, I cannot upload pdf files.
The error messages are:
process: convert PDF to images command: convert -density 150 /opt/red540/webapps/openmeetings/upload/files/e601b2db-eb1b-43cb-8840-6c6639132996/e601b2db-eb1b-43cb-8840-6c6639132996.pdf -quality 90 /opt/red540/webapps/openmeetings/upload/files/e601b2db-eb1b-43cb-8840-6c6639132996/page-%04d.png exception: null error: exitValue: 137 out:

Do you know how to fix the problem?
Also, what kind of files does OM support?

Thanks,

Tom

Thanks for the logs
I have added some guard code to avoid such errors (can be checked using build #91+)

Hi,

When I try to upload a pdf file to my files, the system says "internal error" and cannot complete.
I am using OM4.0. Could any one tell me why this happens?

Thanks,

Tom
