If you made SP Page Builder Pro update or you updated template to latest version
please use FTP tool and delete following folders (only those):

• /heading-title
• /latest_posts

All folders are here: templates/shaper_tixon/sppagebuilder/addons

If you updated SP Page Builder Pro to the last version to get more features from addons, you can also delete following folders: /feature , /icon and /image_content from the template folder only - then Joomla! will be able to use new addons code directly from the component.
