Any site name I specify in global configuration control panel is being duplicated in the browser page title.

This seem to of just started happening and I cant figure out whats causing it.
The only changes I recall recently was a clean install of 3.2.9...???

It only happens i the front end, admin works correctly.

Any ideas would be most welcome, DM.

The template was Yootheme's Way Beyond the trick was to comment out the following line in the template:

$this->setTitle($mainframe->getCfg('sitename') . ' - ' . $this->getTitle());

to

// $this->setTitle($mainframe->getCfg('sitename') . ' - ' . $this->getTitle());

Job done, DM.
