I have encountered itneresting issue here. I am not able to modify / save any settings in the Global Settings as when I click on save I will get this:

Javascript error encountered in method

message: this._currentObject.attrs[m].join is not a functin Filename:

Release 7.0.0_BETA2_2897.RHEL5_64_20101102092658 CentOS5_64 FOSS edition.

Have anybody got any idea what is going on and how to fix this?

Many thanks.
