Hello @corzel yes I believe we have an open issue(s) on this already, if you want to help us debug please feel free or you can open an Issue on the relevant plugin repo instead too --

I'm not sure if this is a duplicate of: https://github.com/littlebizzy/slickstack/issues/30

But since this involves our MU plugin Clear Caches, it should probably be an Issue on that repo instead. Several of our MU plugins are being deprecated, however, and/or will be rewritten from scratch in the near future.
