FOP Could Not Be Configured error after upgrade


I did an upgrade from 2.8 to 2.10 (with 2.9 in the middle) and for whatever reason, I get the following error in the system status page:

"FOP Could Not Be Configured -

An error occured trying to configure FOP. There may be a conflict with another module or there may be permission problems. Check the FreePBX log for more details.

I am not sure which log specifically it is asking me to check, but I did look at ‘full’ and ‘freepbx_debug’ in /var/log/asterisk… couldn’t find anything useful there.

Can anyone lead me in the right direction?
