I configured my SharePoint application to allow anonymous access and it's working fine.
When I add a visual web part that contains just a label to a page and approve it, anonymous users can't see the webpart.
Is there anything that I have to do?
my webpart zone was inside the security-trimming control, after i delete this control my web part works perfectly.
Any change that you enabled the output cache on your page? It behaves different for anonymous users vs logged in users.
p.s. just a wild guess, but the output cache monster got me a few times ;)
