Hello everyone I hope you can help me
What I need to do is to not have the correct top margin
Thanks for your answers
We have lots of templates, lots of margins, there are even two versions of Joomla 1.5 and 2.5, plus all of our extensions. You have posted in the General discussion forum too.
How on earth do you expect anyone to be able to help you with such little information? 
Please post more information, even add a screenshot and notes if language is a problem.
Hope this helps
