FOP2 Community Forum

I have sucessfully installed fop2 in an elastix 2.0.0.58 box.
I also followed sucessfully the directions for change fop in the elastix webgui

After follow all this steps (install and change links in elastix) I proceded to register my fop2 license (also sucessfuly).
After this I checked freepbx and I found some modules out of date and proceed to update freepbx.
Unfortunately after the freepbx update, the fop2 installation messed completely. The buttons suddenly dissapeared.
After a system reboot I was surprised due the old fop panel taked place again in place of fop2.
After this disaster I decided to uninstall fop2 and repeat the earlier instructions for reinstall fop2. But now I always get an empty fop2 (no buttons).
When I run the fop_server -test and also when run the autoconfig-buttons-freepbx.sh I get the follow error
error 1054 (42S22) at line 1: Unknow column 'channel' in 'field list'
From start I installed the version 2.20 for Centos OS i386
