When attempting to use the one-sidebar-left.php block file - which I moved from inside the blocks/mainbody folder to the blocks folder - I cannot manage to place any modules in the sidebar position.
The module is named sidebar in the file.
I have created a module position for sidebar in the templateDetails.xml file.
Also, the module position sidebar does not register in the Template Details / Layout.
Any help in getting this to work would be appreciated.
