Each time I go on the site millesime-beaute.com and click on a link, a page "server not found" appears and I have to refresh the page several times to get rid of it. How can I solve that problem?
Try to clear the cache and the cookies from sites that cause problems.

Also check the settings in your security software (firewall, anti-virus) to make sure that nothing is blocked.
You can check for problems caused by a possibly corrupted user agent.
