This is scaring my pants off... 2 Things...

Note: I have not launched my website and no one purchased a product yet. I've been testing out with different email accounts.

1. For some reason, after you've created an account on my website, then log out, and try to log back in, it WONT let me log in... I Get

"There was a security error when trying to login."

I've read https://www.zen-cart.com/tutorials/i...hp?article=312 but I still don't understand it... I don't even know if the article is related to my situation...


2. When I try to send emails to "customer" accounts, I get

"Mail delivery failed: returning message to sender"

No email whatsoever can be sent to "customer" accounts. Also, when I used "contact us", I CANNOT receive messages properly, it gets sent in "spam" folder of my Gmail account.
Is this because my website is using a Gmail account? Or some other issue?

My website is: a n y c i g a r e t t e [dot] c o m

Any help is appreciated...
