Hi,
Can you please help? Every time I try to post content or change existing content I get page error message at the bottom of explorer (page loaded with errors), and no buttons work. I also can not write anything in the editing box.

Is this a known error and is there a solution?

Thank you!

Is the error on the front-end or on the back-end?

What browser version (IE 6?)? Could you test it with another (e.g. Firefox)?
Is JavaScript enabled?

How do you access the back-end of your site?
with http://www.yoursite.com/administrator or http://yoursite.com/administrator
And how is the $mosConfig_live_site configured in your configuration.php ? with or without www. ?
Please see: http://forum.joomla.org/index.php/topic,87198.0.html

Thanks a lot for a quick reply! It seems that the problem is solved by using FireFox, and the issue still exists if I use IE6 or IE7. I can continue using FireFox for editing and creating content.
Thanka a lot for your help!

You're welcome!
Well, it's not a real solution, but more some kind of workaround....
If you want to use IE, you could try experimenting with it's settings (regarding security / privacy)...

Could you please mark your first message in this thread as "solved" ?
