WP-Otimise

I’ve just started experiencing issues with my website where certain things just stopped working.
It has been traced to the WP-Optimise plugin (has now been deactivated) and everything works just fine.
It could be (as it seems coincidental) that this happened with the WP Update to 6.8.1
[ww.wp.xz.cn … bluehost … Elementor being used].

As I need the caching options .. is it a simple fix OR will I need to go elsewhere for a suitable plugin?

With thanks

David
