I've followed this steps to upload my local magento install my live web server.
Now, the homepage is working fine but every link on it directs you to a 404 not found error. Can't even access "/admin".
I assume this is a problem with the base URL but I've double checked on the database and they're correctly set at "path: web/unsecure/base_url" "value: http://www.mysite.com/"
Anyone got any idea why this is happening?
have you copied the .htaccess file to your server where the rewrite rules are? If .htaccess and mod_rewrite rules are disabled then you can access your admin page via index.php/admin/
The problem is that you have Magento set to use Search Engine Friendly URL's - for example, if you go to http://www.medicalexpress.eu/index.php/quem_somos you will see the page..
This can be caused by:
While you are investigating which of the above is the problem you can get the site working again in Magento by going to the System > Configuration > Web in the admin area (http://www.medicalexpress.eu/index.php/admin and then setting "Use Web Server Rewrites" to No under "Search Engines Optimization"
