Hi I also get this error:
`PHP Warning: Invalid argument supplied for foreach() in /home/benny/onlinegilde/html/wp-content/plugins/fantastic-elasticsearch/lib/nhp/options/options.php on line 257, referer: http://onlinegilde.net/wp-admin/admin.php?page=elastic_search&settings-updated=true
This ends up in a Error 500 and my search isn’t working. So in this case is unusable for me.
I have a vserver with elasticsearch installed locally and php 5.4 and percona 5.5 mysql database.
Maybe you have an idea how to solve this error 🙂
Elasticsearch itself is working because I had before WordPress Xenforo with elasticsearch installed and it worked just fine
