Sorry I accidently pressed enter before without finishing my post.
When I do a:
diff -r /usr/local/fop2 /etc/asterisk/fop2/, I get:
Binary files /usr/local/fop2/fop2settings.db and /etc/asterisk/fop2/fop2settings.db differ
Maybe manager is writing the changes into one file and reading from the other?
The general error:8 I got when I copied fop2settings from /etc/asterisk/fop2 into /usr/local/fop2
