Asset CleanUp’s object cache is not valid.

@advi as long as it doesn’t affect the functionality of the plugin, you shouldn’t worry about it.

I double-checked the situations where this log might have occurred and I suspect it’s happening when there’s no object cache set and it’s incorrectly checked if it’s null or not before being filled with anything. I’ve done some improvements and now it should be better. Can you install the development version instead of the current one you have now? Here’s how to do it: https://www.assetcleanup.com/docs/how-to-get-the-development-version-of-asset-cleanup/
