Elasticsearch-head plugin not available through http://localhost:9200/_plugin/head/

Elastic Stack Elasticsearch
1

i just upgraded to latest elasticsearch 0.20.2 and reinstalled the head
plugin, but i can't open it through the browser:

http://localhost:9200/_plugin/head/

the installation is fine, its installed into
/usr/local/var/lib/elasticsearch/plugins:

○ → ls /usr/local/var/lib/elasticsearch/plugins/head/_site/
LICENCE README.textile index.html lib

when i open
file://localhost/usr/local/var/lib/elasticsearch/plugins/head/_site/index.html
the plugin is there as expected.

is there some new configuration option, that needs to be enabled to run the
plugin? or did i miss anything related to site plugins?

Are you sure you open it with the ending slash "/"?

Yeah, I open it with the trailing slash. We need more information about
what error you are getting? 500? 404? Timeout?

I just tried it with a fresh installation of elasticsearch and it works
fine. How did you install it?

i installed via homebrew. re-installing elasticsearch did not help, but
brute force did the trick:

rm -rf /usr/local/var/lib/elasticsearch/

now everything is fine, except that all indexes are gone :slight_smile:

stopped working again... no logs, nothing :frowning:
