Yes, that was the problem. I upgraded to php5 which i thought its the deafult on my hosting and the issue got resolved.


Thank You,

Joomla! 1.5.3
VirtueMart 1.1.3
JoomSEF Version: 3.6.2
JoomSEF VM extension version 2.0.30

Pretty much everything works except 1 thing,

on some categories there are more that 20 product and VM create a 2,3..page. but when JoomSEF is one those links don't get rewritten. and i get the error.


Fatal error: Call to undefined function: array_diff_key() in the
path to website/htdocs/components/com_sef/joomsef.php on line 887

the link that gives this error is something like this..

domain.com/store/cures?limit=20&limitstart=20

where "cures" is the name of the category...is there any way i can mannually add the writing rule to joomsef? i've purged and cleared cache and updated the link couple of times.

TY
