Every time I try to load the session file, I receive an error message stating that the session cannot be loaded. However, after clicking “Ok”, both Dragonfly and Wizard function normally despite the error. Why is this happening?

Hi @Jenny,

Can you please be more specific? What’s a session file, and what’s Wizard?

Dragonfly is a modern Redis replacement with multi-threaded and shared-nothing architecture. It’s a high-performance in-memory data store. I’m not familiar with the terms you mentioned, so I’d like to make sure you’re posting in the right place.

Please let me know if I am missing something or help me understand the software you’re using.

Thanks.
