Check the client log for errors. You can also do bbb-conf -c and see if that gives you any suggestions. If not, check also the logs for bbb-web.

One easy thing to do is bbb-conf --restart and see if that fixes the issue

Can you check on /var/log/bigbluebutton/bbb-web.log on what may be the
root cause?

You can post the log in pastebin.com so we can take a look.

Hi David,

The log says exception error because a dir exist...can you please tell
us what dir? Or post more of the logs into pastebin.com so it formats
nicely?

Please post the log as many lines as you can.

Hi Richard

Already published at this time.

Your paste: http://pastebin.com/Xivju7EJ

What is the directory that should I check?

Thank.

What I mean is open /var/log/bigbluebutton/bbb-web.log then cut and
paste the last 1000 lines.

The log above what you have provided may give a clue on what's wrong.

Did you install using the VM? Packages? Or manually?

What is your system?

It looks like there is a problem with the permissions.

When you upload 62.pdf, it tries to create a folder under
/var/bigbluebutton/<confname>/<room>/ with the presentation. The
PresentationService tries to delete the directory and create it but it
can't.
So the check (dir.exist()) if it has successfully created the directory failed.

Check what process is running tomcat and if it has rw access to
/var/bigbluebutton. I think the packages assume the process is
tomcat6.

I am very grateful to Richard, you change the permissions to / var / bigbluebutton and fix the problem.

Thank you.

David.

I know this is two year old post but I just want to share how to fix this problem if any one stumbles upon it:

Just run: sudo find /var/bigbluebutton/* -type d -exec chown -v tomcat6:tomcat6 {} \;

That should fix permissions.
