Hi there, hope you can help me out here.

I got JoomSEF working great locally in a MAMP environment but now I have uploaded the site to the live server it does not work. I am using the .htaccess as instructed in the documentation.

The server is a Linux dedicated server from Fasthosts so I don't get much in the way of support from them.

Could you point me to somewhere I can find out how to fix this please?

Steve

Oh yes, the site loads but all menus take you to a 'NOT FOUND' page.

Please check our FAQs - http://www.artio.net/en/product-faq/joomsef-faqs - regarding 404 error.

Most likely, this might be wrong RewriteBase value if your site is not in domain root, or if you are using JoomFish, the publicaiton of JoomSEF MetaBot and JfRouter at the same time.
Also make sure you caches were cleaned after site move.
