SEF breaks VM2 links at site but not others

[Anthony E. Alvarez]

Enabling Search Engine Friendly (SEF) displays VirtueMart error messages instead of links at site. All errors seems to be caused by same file at same line number however. Same error messages appears in modules My Cart, Categories and product pages.

For Example:

My Cart

Code Select Expand

Warning: Illegal offset type in isset or empty in /home/p/public_html/libraries/joomla/application/menu.php on line 127
Cart empty

Warning: Illegal offset type in isset or empty in /home/p/public_html/libraries/joomla/application/menu.php on line 127

Categories

Code Select Expand

Warning: Illegal offset type in isset or empty in /home/p/public_html/libraries/joomla/application/menu.php on line 127
Accessories

System Setup

• VirtueMart Version: 2.0.18a
• Joomla: 1.5

When SEF is turned on, other pages render properly. Only VirtueMart Modules are affected.
Any clues appreciated. Please help. Thank you.
