mysqld: Query cache disabled?

[Richard Shaw]

I was using mysqltuner perl script on my mythtv machine and it's
telling me that "Query cache is disabled" and that "Thread cache is
disabled" even though I think I have the relevant options set in
my.cnf:

# mysqltuner script tuning options
skip-external-locking
query_cache_type=1
query_cache_limit=3M
query_cache_size=32M
join_buffer_size=512.0K
tmp_table_size=32M
max_heap_table_size=32M
thread_cache_size=8
table_cache=256
key_buffer_size=64M

Any ideas?

Thanks,
Richard
