Login Time Out after entering credit card details?

[TwoWayRadio]

Yes, I know that.
The zenid can be removed from URL at our two sites, also the sites don't show "Login Out Time" message.
Just one site can not work at this cause. so we very confuse why have these different result, can you give me information for zenid?

Jarvis,

Did you manage to sort this in the end? We have a similar issue as we've had to strip our zenid to go to the merchants payment pages...

I was having a similair problem. I received a "Whoops! Your session has expired" error everytime a customer went to checkout. Additionally, the Zen Cart would revert to showing "Log In" instead of "Log Off" immediately after Loggin in. Also, I was receiving an "About:Blank" Page IN BETWEEN every page after logging in. (This WIPED out the session.

Here was MY solution:
1) Went to phpMyAdmin and opened the zen_sessions SQL File and then did a "Repair Table" command from the Table Maintenance area under the Operations area.

FINALLY, after days of not having orders..., The site now works again!

Hope this helps someone.
