Fatal error: Class 'KalturaConfiguration' not found in /var/www/visalus/sites/all/modules/kaltura/kaltura_client/kaltura_helpers.php on line 235

Looks like the KalturaClient library is not loaded in that class. I was able to hack/fix this by loading the library manually in getServiceConfiguration(). Anybody else getting this?

I can confirm that I am also seeing this error on field settings pages and during cron with version 2.1

I got this error after upgrading the Kaltura module from 2.0 to 3.1. After reading the Kaltura Manual, I realized I needed to install the new Kaltura library. This is easily done in drush with:

drush kaltura-client-install

Actually, there error is reappearing even after installing the Kaltura library with version 3.1 of the module. The source of the error is now kaltura_helpers.php line 152. Any ideas on what's going on?

Got the same issue Fatal error: Class 'KalturaConfiguration' not found in kaltura_helpers.php on line 152

Any idea?

Make sure to clear your cache after installing the kaltura client under sites/all/libraries. That solved it for me.

I even clear cache, still cannot connect to my local Kaltura CE server.

This is caused by the libraries module not finding a version in KalturaClient.php eg:

$this->setApiVersion('3.2.0');
protected $apiVersion = '3.1.6';

I created a patch for this problem. Also, make sure you use the library supported by your Kaltura provider, not the version downloaded using drush.

I followed all the advice here and still kept getting the same error regarding line 152.

I found a solution that worked for me, though. As a last ditch effort, I reinstalled the library using the 'drush kcdl' command and told it yes to overwrite the existing Kaltura Client. As soon as I did this, Kaltura is now working for me.

May not be a solution for everyone, but maybe it'll help someone out there.

#8 worked for me, after I cleared cache.
