If you are using a version of phpBB2 as part of a nuke installation, it is NOT a copy of the files from here.
Or more correctly, it is a greatly altered copy, of a VERY old version, of our v2 line.
As such it is only a distant relative of the software we have been supporting as v2.0.23
As said before, you need to talk to the nuke support sites about this, any advise you might have from here could seriously damage your installation.
