master page not up to date in preview mode

Chris,

Can you confirm what you mean by you 'cleared the cache'? Did you do this in your browser or at the Kentico system settings? Is your script inline in the Master Page or an included JavaScript file? If it's included, are you using the Kentico JavaScript component or storing it on the server? This could really be a few things going on, so if you can provide some of those answers might be able to point you in the right direction.

Yep, under Content Management -> pages, on the root page -> master page tab, there are a few paces I can enter html. The section that is still in the head tags is where I've added a script tag. After this has been saved I can see this when I view source only if I'm not in preview mode.

On the root page In the general tab I've set "use cache output" to no, "allow file system cache" no and clicked "clear output cache" and saved the page.

In Debug I cleared the cache and I've gone to System, clearing unused memory, performance counters, cache and restarted the application. In IIS I've stopped the site, restarted the app pool, started the site and cleared my browser cache and in preview mode that content still won't show. I've tested in other browsers too, in all of them it's only broken in preview mode.

Clear your browser cache as well.

Thanks Jan, I've applied the latest Hotfix and that's worked.
