Edit Site News error!

I am using CS-Cart 2.0.10, and I am getting some weird error while editing site news!

Login as Administrator, go to Content > Site news. Click on to edit an existing news item. Click on Save. In IE, I see HTTP 500 error. In Firefox I simply see a blank page!

What is happening here? Anyone facing the same problem???:confused:

Anyone using CS-Cart 2.0.10 can give this a try and let me know if you hit any error like me? Thank you!
