I have the same issues
Downloaded sef 3.1.1 then paid for the virtuemart plugin oh which by the way does not work, it will not even install. and i have the sef link on the site.
Oh i have these error's
Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/xxx/public_html/administrator/components/com_sef/views/templates/default_extslist.php on line 53
Warning: Invalid argument supplied for foreach() in /home/xxx/public_html/administrator/components/com_sef/views/templates/default_extslist.php on line 53
And yes the sef_ext directory is readable and executable befor you ask.
You guys do not make it clear what the hell we are supposed to buy and not buy, i see payment for sef 3.1.1 but then you can download it for free also hu? , i suppose that the 30 euro payment one is to remove the sef link to your site, or is this the sef component that does actually work with joomla 1.5.3 ???
I am starting to get really frustrated with all these people that claim to have a sef component that does work i have spent an entire day going over three of the top sef components and not one of them works with virtuemart.
All be it your sef 2.2.6 works great with the VM plugin i bought for joomla 1.0.15 congrats on that one but not for 1.5.3 yet. Let me know when you get this component working like 2.2.6 but in the mean time please give me my money back.
