Hi!! Right now I am trying to migratemy ser.cfg file from ser0.9.7 to ser 0.10.99 when I try to check the ser.cfg file structure I get errors: 0(28672) parse error (252,16-17): unknown command, missing loadmodule? the errors correspond to the following line in the ser.cfg file: www_challenge("scscf.ims.touk.pl","0"); if (!check_to()) { proxy_challenge("scscf.ims.touk.pl","0"); } else if (!check_from()) { below is the list of my loaded modules: loadmodule "/home/ser/src/ser-0.10.x/modules/ctl/ctl.so" loadmodule "/home/ser/src/ser-0.10.x/modules/mysql/mysql.so" loadmodule "/home/ser/src/ser-0.10.x/modules/sl/sl.so" loadmodule "/home/ser/src/ser-0.10.x/modules/tm/tm.so" loadmodule "/home/ser/src/ser-0.10.x/modules/rr/rr.so" loadmodule "/home/ser/src/ser-0.10.x/modules/maxfwd/maxfwd.so" loadmodule "/home/ser/src/ser-0.10.x/modules/usrloc/usrloc.so" loadmodule "/home/ser/src/ser-0.10.x/modules/registrar/registrar.so" loadmodule "/home/ser/src/ser-0.10.x/modules/auth/auth.so" loadmodule "/home/ser/src/ser-0.10.x/modules/auth_db/auth_db.so" loadmodule "/home/ser/src/ser-0.10.x/modules/uri/uri.so" loadmodule "/home/ser/src/ser-0.10.x/modules/uri_db/uri_db.so" loadmodule "/home/ser/src/ser-0.10.x/modules/domain/domain.so" loadmodule "/home/ser/src/ser-0.10.x/modules/mediaproxy/mediaproxy.so" loadmodule "/home/ser/src/ser-0.10.x/modules/nathelper/nathelper.so" loadmodule "/home/ser/src/ser-0.10.x/modules/textops/textops.so" loadmodule "/home/ser/src/ser-0.10.x/modules/avpops/avpops.so" loadmodule "/home/ser/src/ser-0.10.x/modules/xlog/xlog.so" Are those functions not present in ser 0.10.99 any more?
