blank pages (navigation issues) after login into site

[biodunduro]

Hello Everyone,

I'm new to CMSimple, but quite familiar with CMSs generally.

I deployed CMSimple SE 2010c (based on CMSimple_XH 1.1.2) here (http://www.privatemediamart.net/)

Everything works well, until I decide to login and edit text or do some other things. Then I start to get blank pages, and it becomes very difficult to do any navigation. Upon Refreshing several times, I get the page to display, and discover that I have successfully logged in. But navigating from there presents the same problem - blank pages.

Also, when I click on the 'Svarrer Gallery' link, I get the following error message:

"Gallery Plugin Error :Gallery plugin detected that someone already had sent headers

Solution : Look for the error in /home/privatem/public_html/plugins/bannerrotator0.2/index.php line 31, typical a space or empty line"

Could the problem be caused by the bannerrotator plugin, even though it has not been deployed?

Will appreciate your help.

Thanks.

Sorry, some additional information.

Everything works fine on my localhost.

I'm using Internet Explorer 8. I've also tested on Firefox and Chrome browsers, and experience the same thing.

Thanks.
