It’s probably unlikely anyone here will know much about how a commercial theme is set up or coded…as we don’t have access to them and they’re not supported here.
Have you considered finding a theme that IS supported? In the long run, you’d really be much better off not using a theme that’s likely to have increasing compatibility issues going forward.
I would love to try and find a new theme, but that is not going to be on the priority list for a while. I was hoping there was a plugin that I could use that would provide access to determining where the sidebar was, regardless of the theme?
I don’t know of any plugins that will do that – but see if adding this CSS will:
.category #sidebar {
float: right;
margin-right: 0;
}
.category #page-content {
clear: none;
}
