with absolute path to moses-tm.ini does not resolve the problem. Still get the same error.

This is what I get when I run the same command as you:
LexicalReordering0= 0.300000 0.300000 0.300000 0.300000 0.300000 0.300000
Distortion0= 0.300000
UnknownWordPenalty0 UNTUNEABLE
WordPenalty0= -1.000000
PhrasePenalty0= 0.200000
TranslationModel0= 0.200000 0.200000 0.200000 0.200000
Looks just like your output. However, this is what I get when I run the mert script with the following command:
/media/bigdata/jcread/llv/data/europarlv7/raw/aligned/bg-en/training_data$ /media/bigdata/jcread/3rd_party_software/mosesdecoder/scripts/training/mert-moses.pl -no-filter-phrase-table ../tuning_data/true.bg ../tuning_data/true.en /media/bigdata/jcread/3rd_party_software/mosesdecoder/bin/moses binarised/moses-tm.ini --mertdir /media/bigdata/jcread/3rd_party_software/mosesdecoder/bin/

The following weights have no feature function. Maybe incorrectly spelt weights: LM0,Exit code: 1
The decoder died. CONFIG WAS -weight-overwrite 'PhrasePenalty0= 0.043478 WordPenalty0= -0.217391 TranslationModel0= 0.043478 0.043478 0.043478 0.043478 Distortion0= 0.065217 LM0= 0.108696 LexicalReordering0= 0.065217 0.065217 0.065217 0.065217 0.065217 0.065217'

looks fine to me. This is what I get when I used it to run
# $MOSES_DIR/bin/moses -f moses.ini -show-weights
....
LexicalReordering0= 0.300000 0.300000 0.300000 0.300000 0.300000 0.300000

PhrasePenalty0= 0.200000
TranslationModel0= 0.200000 0.200000 0.200000 0.200000
Double check that the moses.ini file you sent me is truly what you're using.
To be sure, you MUST use absolute paths for all file names, ie. not
binarised/moses-tm.ini
but
/media/bigdata/whatever/binarised/moses-tm.ini

there lies your problem. There's a weight for a non-existant feature function

did you delete the line

too?

The following command works fine for when a language model is specified. Deleting the line KENLM lazyken=0 name=LM0 factor=0 path=$PWD/blm.en order=3
