Just recently I updated our Zencart to the latest version, it was long overdue as the website hadn't been updated for around 5 years.

Everything else is working fine except I've had a lot of issues with customers not being able to log in to the website, through tests I have found this is most frequent while using Google Chrome.

Customer's get the message "There was a security error while trying to log in."

I have searched through and through about this problem and I can't seem to find a solution anywhere. I've also tried the remedy at https://www.zen-cart.com/tutorials/i...hp?article=312

My cart is http://www.endemicskatestore.com

Any help would be much appriciated!
