Slider doesn't show up - JB Library Plugin

Error

Slider doesn't show up in frontend, there is only an empty space.
Javascript errors:

  • TypeError: window.nextend is undefined 
  • TypeError: id is undefined
Solution

This problem could happen, if you have JB Library Plugin installed in your Joomla website. In that case you should go to the Extensions -> Plugins (Plugin Manager in older Joomla versions), filter out the system plugins, and put the Nextend2 Library after the System - JB Library plugin. You can reorder the plugins by clicking on the arrows next to the top checkbox, and drag 'n drop the plugins with the squares next to their checkboxes.
