Slider Revolution does not work properly

If your slider made with Slider Revolution is not working as expected, e.g., changes are not visible, animations do not work, or the slider does not load at all, it could mean that Frontend Engine is the culprit.

Go to Slider Revolution → Globals, and change the rendering engine to SR6:

If you want to use SR7 rendering engine, you should follow the update guide available on the official Slider Revolution website: Update Guide.
