Log-in problems

Dear all,

Here in the last time (from version 6.00.300 - > 6.00.302) I had a strange problem at my site (www.dansk-thai.dk).

On my site, I mainly have users from Denmark and Thailand. And I had not heard about any users with the problem in Denmark, only among users living in Thailand.

The problem is that the users in Thailand log-in on eachothers profiles, and can change the information, write in the shoutbox and in the forum with the other users profile. They can't choose another users, it just happend by it self and random by all the users in Thailand. If close the page and opening it again then they maybe are logging in with their own profile or another user again.

I had asked the users who reported this to me, if they use same PCs as other users and most of them even not know the other members in Thailand.

Did you heard about this before, and do you have any idea about what is wrong and how to solve it ?

It's a big problem now, and I had never heard about it from any users before version 6.00.300 and still nobody has reported it to me here in Denmark - only users from Thailand.

On of the users travel a lot in both Thailand and Denmark and only use his notebook in both countries, but only meet the problem when he is in Thailand. Could it be a local proxy-server problem in Thailand ???

Sorry my bad english, I hope you understand what I mean even it sounds some unclear for me too. I simply not understand what the problem can be and it's impossible for me to dublicate because I'm in Denmark.

Hope you have time to take a look on it and hear if any other meet similar problems here in the last time.

Thanks
