elasticsearch can't install head plugin

Question

I am planing to install head pluging for elasticsearch.

in both these two official documentation, http://mobz.github.io/elasticsearch-head/ and http://docs.couchbase.com/admin/elastic/install-plugin.html they said to use this:

bin/plugin -install mobz/elasticsearch-head

I did, but i got the following error:

PS C:\elasticsearch-1.3.9\elasticsearch-1.3.9> bin/plugin -install mobz/elasticsearch-head

as I was trying to diagnosis the error, I found that there might b something wrong in elasticsearch.yml file. I went to that file, and opened it using notpadd++, and it was all commented except the last three-four lines, they were letters not understandable. this is a print screen of them:

could you help please

In that file you shouldn't have those chars. Remove them and start over. Or take a clean instance of ES, take the config file from that and use it. — Andrei Stefan, May 31 '15 at 10:46
@AndreiStefan i unziped again the ES file and I browswerd to that file again, i looked at it, it doesn't have any wrong character. can I replace it with the orginal (corrupted) one? knowing that I already did all the steps here http://docs.couchbase.com/admin/elastic/install-plugin.html and I arrived to install `head` plugin — Marco Dinatsoli, May 31 '15 at 10:54

I got a new problem and it is related to what you have told me to do. when i replaced the new yml file, the password for 127.0.0.1:9091 is not working. maybe it was written in that file? because i have done `echo "couchbase.password: password" >> config/elasticsearch.yml ; echo "couchbase.username: Administrator" >> config/elasticsearch.yml` before, what should I do please? i want to make a replicate for couchbase and I need the password – Marco Dinatsoli May 31 '15 at 11:16
Copy the configs you had in the old file to the new one. Of course, except the faulty chars. – Andrei Stefan May 31 '15 at 11:21
you should have told me that before, anyway I will try now, thanks – Marco Dinatsoli May 31 '15 at 11:22
Sorry, not in front of a computer or phone frequently today. – Andrei Stefan May 31 '15 at 11:48
