Hi there,
Thanks for writing in! According to our Changelog latest compatible version of Revolution Slider is v5.1.6. So the latest update that Themepunch just released is not available yet on Themeco end. If you have separate license for this, you can update but it’s not recommended. You should use the compatible version to avoid any potential conflict.
So I’d suggest you to use v5.1.6 for now and wait for next update while we test the compatibility with the new version.
Cheers!
