Snow Doesn't Switch Off

I’ve used your plugin for a couple of years and have had no problems with deactivating it.

Today I tried to deactivate the snow – it didn’t switch off. The snowflakes simply became white blobs.

I uninstalled the plugin – the white blob version of the snowflakes remain. I reinstalled and reactivated/deactivated, and the snow is still showing.

Could you advise me how to turn the snow off please?

Many thanks.
