Please see Talian 5 Theme Support for Talian 5 theme support. There’s a LOT of useful information about Talian 5 usage on that site.
Please note Talian 3, 4 and 5 customer who ordered before March 2011 (before the official Stallion 6 release date) were entitled to a free update/upgrade to Stallion 6. This offer ended after Stallion 6 was released early March 2011.
During Stallion theme activation enter your Talian theme order email address into the Stallion ID Reminder Form to obtain your Stallion ID automatically by email (takes a minute).
Stallion 6 though an upgrade/update of Talian 5 I rewrote a lot of the coding, so though Stallion 6 looks like Talian 5 it’s a new WordPress theme (I could make Stallion 6 look like almost any WordPress theme), so it’s not really an upgrade/update per se.
