Bad Request error when saving configuration

Good Day

I have installed OS Property without any problems, but when I try to save changes to the configuration I get a "Bad Request Your browser sent a request that this server could not understand." error message. I've looked up this problem in the Joomla Forum, but have not found anything that could solve this problem yet.

I have SEF enabled, mod-rewrite disabled, no cookies settings in my Joomla configuration. I have a Joomla 2.5.7 installation.

Any help would be appreciated.

Thank you

Hi

I'm also getting this in IE9 - I've cleared the cache and deleted cookies.

Hi,
If it's the configuration part in the backend, can you please try in another web brower. If you still have the same problem in another web brower. Please read above reply of us and send me your site information with backend account to damdt@joomservices.com. I will check to confirm the problem with you.

Hi Dam, I've sent you my backend details.

With Dam's and my hosting company's help we figured out that it was the mod_security setting on the server that needed tweaking. This matter has been solved. Thanks to all.
