Hi

The best way to get the support is Contact your purchased item Author. Contact Author and let them know.

Thanks

Hi Maattandtechniek,

Thanks for using Slider Revolution. Based on the error message, it looks you are using an older version of the plugin. As you have received our plugin via a theme purchase, there are two options:

  1. For setup and integration issues, please contact the theme author directly. If you want to update the plugin, you will have to wait for the theme author to include the latest version in their theme. With the latest plugin .zip file you can then do a manual update as explained here https://www.themepunch.com/faq/update-to-5-0-via-ftp/

  2. If you need direct support from us as well as automatic updates in the backend, you can purchase a plugin license from us here https://codecanyon.net/item/slider-revolution-responsive-wordpress-plugin/2751380 . The license key you receive can be entered in the plugin backend and will unlock the automatic update feature for you. When commenting on the envato item page or submitting a ticket to our support system https://themepunch.support/

If you’ve further questions, feel free to email us at help@themepunch.support

Thanks!
