So If I make a change to java Script or a thread hits it's limit, the site takes awhile to accept the changes and update the users or the java Script. Sometimes even the CSS does not update straight away.

Any idea why this would be happening or something I can do to fix this issue?

Clear the cache & then check.

If clearing your cookies & cache does not help, try re-synchronizing your forum.

Hi,

In addition to that, this it the tutorial for clearing browser's cache:

I had all that, but it seems to have fixed it'self over time and now seems to be working fine.
