I just changed my site´s theme, so I had to adjust it to the layout of my new theme (Mantra).
I was replacing the widgets and everything was ok, until I added a text widget (ad) on the "above content" widget area. Then, the content of the left sidebar wet down. I deleted what I had just added, and nothing happened, deleted the content of the left sidebar and put it back, and still... I put back the "above content" ad and still there´s a blank space before the widgets of the left sidebar appear.
I haven´t made any css changes at all, I just used the widgets menu.
My site is http://www.practicaryoga.com
What could be wrong?
