Tableau Responsive Theme - Support Thread

[flax]

Select Tools - Template Selection then hover over the Tabelau icon and you'll see Configure as a clickable button.

I tried to change some configurations after hovering over the Tableau icon and clicking configure... the configuration page is OK but when I try to save any change I get a Forbidden message which says that I don't have permission to access the template_select.php file in the admin (renamed) folder

It's the latest Tableau version in a 1.5.3 clean install with no modifications of any sort that seems to work with no issues so I imagine I'm missing something stupid... any hints or suggestions?

Thanks and happy new year :)
