I installed Jomsef 3.1.2 on Joomla 1.5.5. with Virtuemart 1.1.0.
on the site it shows the following error:
Notice: Undefined index: com_virtuemart.xml in my_site\administrator\components\com_sef\classes\seftools.php on line 168

Notice: Trying to get property of non-object in my_site\administrator\components\com_sef\classes\seftools.php on line 168

the error appears in the top of the page, but the site works.

could you kindly help me to fix the problem.
thank you

Hello,

This problem is caused by a bug in JoomSEF, it will be fixed in next version. You can get rid of the errors by re-saving JoomSEF's configuration.

Best regards,
