Issue with Call To Action plugin

Self-hosted single server CE 11.5 RPM on Centos 6.7

I copied the following text displayed in the Player Studio tab on page http://player.kaltura.com/docs/ActionButtons and pasted in the Universal Studio player Import Plugin section:

actionButtons.plugin=true&actionButtons.displayOn=end&actionButtons.customDataKey=ActionButtons&actionButtons.openInNewWindow=boolean&actionButtons.actions=[{“id”:“product”,“label”:“Buy this Product”,“url”:“http://www.myproduct.com”},{“id”:“product2”,“label”:“Read more about this Product”,“url”:“http://www.myproduct.com”}]&actionButtons.templatePath=…/CallToAction/templates/action-buttons.tmpl.html&related.plugin=true&related.itemsLimit=5&metadataProfileId=3416131&inlineScript=false

Call to Action buttons do not display at the end of the video. Please advise. Thank you.
