I recently installed !JoComment 4.0 alpha3 on my site http://www.techportal.co.za

I tried out the advertising space using the standard banner code.

I placed some google adds in the code, but the code is repeating one, so everything is showing 2 times.

Does not matter what I enter, eg. hello it will display hello hello

Is there any fix for this? I'm scared if I upgrade to the latest version I loose my current data?
