Error in revslider after updating to 6.8.12

Support
#1

Hi,

After updating the Pro theme to version 6.8.12, the site hotelterra.es is showing the following fatal error on wp-admin/plugins.php:

“call_user_func_array(): Argument #1 ($callback) must be a valid callback, class RevSliderAdmin does not have a method ‘add_ajax_footer_functionality’”

I have RevSlider 7.1.4 installed. I’ve already fully reinstalled the plugin via FTP and the error persists. I noticed in your changelog that this type of issue (“RevSlider was using a deprecated method on version 7”) was fixed in 6.8.6, but I’m still getting the error on 6.8.12.

Could you let me know if there’s a specific RevSlider version compatible with Pro 6.8.12, or if this could be caused by a partial theme update? I can provide FTP/WP access if needed.

Thanks.

Hello @Juanjo,

Thanks for writing to us.

I tested this on my local installation and was unable to reproduce the issue. It is working as expected with the following environment:

  • Pro Theme 6.8.12
  • WordPress 7.0.2
  • Slider Revolution 7.0.15
  • PHP 8.2.4
