I use the template Maelstrom, how to publish three positions in "Main body positions." My problem is that I have two menu when you click to read the article like this link:http://isabu-bi.org/index.php?option=com_content&view=article&id=73&Itemid=86&lang=fr
yes that would be the sidebar-b position. So if you ahve modules in sidebar-a and sidebar-b you have two side columns but you may have to use the layout silders in the template manager to get the sidebars on either side of the mainbody.
I can detail the method to follow please, I speak little English and the tutorial is in English.
Do I need to know coding in php to make the requested changes,
I find that in the sidebars in the template layout silders manager.
Thank you forYour help.
