Upgrade Joomla 3.1.5 to 3.2 fails with the latest JoomSEF 4.5:

PHP Fatal error: Unsupported operand types in /home/example/public_html/libraries/joomla/application/router.php on line 182
PHP Fatal error: Call to a member function setActive() on a non-object in /home/example/public_html/components/com_sef/sef.router.php on line 371

I have this error too (Joomla 3.2.1 and JoomSEF 4.5.1):
PHP Fatal error: Unsupported operand types in /home/example/public_html/libraries/joomla/application/router.php on line 182

This is on line 182 in router.php: $vars += $this->_parseSefRoute($uri);

Same problem here ...
Artio team, some idea ??

I had the same issue and I deleted that file (I think it is a leftover from an older version as it was not present in other J3.2 sites I have.

Try renaming it and see what happens.

I guess you're right sambob.
The error has gone since I updated to Joomla 3.2.2.
Also the file /public_html/libraries/joomla/application/router.php isn't present anymore after the update.
