Redeclare issue every time I save

Hey everyone.

I can create a snippet & activate it, no problem. But when I try to edit it, and save it again, I get the “Cannot redeclare function xxx”. This de-activates the code which is super annoying.

I’m 99% sure this is a server config issue, as I use Code Snippets a lot and this is never a thing. Any one got any ideas what to check?

Thanks.
