How curl is connecting the plugin to the solr server ?

Can you test out the following fix ?

Line 364 of file wp-content/plugins/wpsolr-search-engine/classes/solr/wpsolr-search-solr-client.php

replace

$config = array(
endpoint' => array(
				'localhost1' => array(
					'scheme'   => $solr_index['index_protocol'],
					'host'     => $solr_index['index_host'],
					'username' => $solr_index['index_key'],
					'password' => $solr_index['index_secret'],
					'port'     => $solr_index['index_port'],
					'path'     => $solr_index['index_path'],
					'timeout'  => $timeout,
				)
			)
		);

with

$config = array(
			'adapteroptions' => array(
				'proxy' => null,
			),
			'endpoint'       => array(
				'localhost1' => array(
					'scheme'   => $solr_index['index_protocol'],
					'host'     => $solr_index['index_host'],
					'username' => $solr_index['index_key'],
					'password' => $solr_index['index_secret'],
					'port'     => $solr_index['index_port'],
					'path'     => $solr_index['index_path'],
					'timeout'  => $timeout,
				)
			)
		);

I’m sorry, but I can’t find any 'endpoint' => array( in wpsolr-search-solr-client.php…

It’s the 7.4 downloaded from the www.ads-software.com repository.

My mistake.

It’s wp-content/plugins/wpsolr-search-engine/classes/extensions/indexes/option-indexes.php

Ok, found it ! I’ll tell you when I’m done.

Unfortunately I still have the same error. But still, thank you for your help.

You mentioned 2 Solr instances, for Drupal and WordPress. And also that the Drupal/Solr is working fine.

What are the respective Solr ports ?

What is your OS ?

The server is running Ubuntu 12.04.

For the ports, it’s a different one for each installation. For drupal, I’m using 9026 and for wp, it’s 8926. And other students are using other ports. All theses ports are open, but only locally.

On the local network, I can reach the web admin of each of these solr installation.

I’m using the 4.10 version of solr.

Can you switch WPSOLR port to Drupal’s (9026) ?

Just change the port, and save the index configuration. WPSOLR will test the connexion.

I did, but I got the same error.

Which Drupal Solr module do you use ?

apache solr : https://www.drupal.org/project/apachesolr

Do you use https ?

No, we’re in http.
