I am also getting this error, as well as the google membermap sending me back to the forum list .... any ideas ?
Should be fixed in the upcoming JSMF 2.0.
Regarding the "SMF Mod" - is this referring to the SMF 1.1RC2-1 security patch ? Does it need to be re-installed after installing JSMF 1.1.4.2?
If I recall correctly, the SMF Mod (for SMF) was only required for very old versions of Mambo-SMF. So you can safely ignore #2 for now. Someone please correct me if I am wrong!
