I don't know, I would have to take a look at it. It's possible that our lattest version will solve this problem, but you need to have an active subscription to download it...

Thanks for your answer

hello,

you can't have our latest update because it's just 1 week old..! version 1.4.8...

To access your site, you need to have an active subscription.. otherwise I can't give technical support...

Yes i understand, so have take the subscription and with last update have the same problem.
So its very strange, with admin account on my website i don't have problem

hello!

ok, that is strange that you are getting the same problem.

Ok, please send me joomla access data at support@ joomlathat.com and I'll take a look.

you say that the problem does NOT happen in admin? where does it happen? on frontend only?
