Customer Login CROSSED With Another Customers Login

**zapme1** · 27 Jul 2019, 01:31 AM

I'm running Zen Cart v1.3.9h, and PHP Version 5.4.45. My website was installed in 2010, and has been "Heavily Modified" over the years. I do not sell physical products, but instead my products are "Training Class Dates", and my customers purchase a "Seat" in my classes!

I know that I should have updated my site (probably long ago), but it would be a nightmare with all of the modifications. The site works well, however only once in awhile a customer will call to tell me that when they went to login to their account, they found that they were "Already Logged Into Another Customers Account"!!!

I have seen this myself a few times by simply visiting my main page, and refreshing the page! I would then already be logged into a customers account that had just purchased a seat in a class from my site! If I Logout, then all is back to normal, and I can login myself just fine!

Like I said, it does Not always happen, and I can't recreate the issue, but I've seen it about 4-5 times in a year, but hard to know how much it happens to other customers!

Does anyone have any ideas?
Thanks in advance.....!

Please don't double post. This posting was already made. Perhaps the post button got pressed twice in a row, but there is not yet indication that was the cause.
