I'm not sure what you mean by your site not being secure, but if you mean it's still under development, then we're very used to seeing sites in various stages of undress.

Those of us who are more interested in the design and layout side of Zen Cart (though I think Linda is understating her abilities here) have an armoury of tools that we use to lift the hood of misbehaving sites and then prod and poke them until a solution emerges. Sadly this is rarely possible from a screenshot.
