Free extensions for Joomla!

Hi

I have installed XMAP and now I'm having trouble saving the frequencies and priorities.

It says you can change the on the webpage if you are signed in as a super administrator. I can do this and I can change all the frequencies etc but it does not save and it reverts back to the previous settings. This only seems to happen with virtuemart products within the sitemap.

I would just change the defaults for the virtuemart but I have 3 different variations for categories, sub categories and Products and the plugin only gives options for 2.

Hope you can help

Simon
