I think bytes_log is NOT a default selection in the builapache.sea cpanel provides (on layer 1) It might have been in the past, but I don't think it is any longer.
And I don't think it is instilled by default in the fp-5.0-upgrade (no choices) self extractor, either.
So, just rebuild with buildapache.sea and make sure you select it- if this is a new system like it appears, you should have no problem at all.
