Hey Shaun,

I am really sorry for the delay of this reply as it is a weekend for us here. I believe it could be due to the ACL configuration within JCE because JCE has an ACL layer that determines which user groups are allowed to access the toolbar.

If you have already configured that and it still isn't displaying, probably there are some script conflicts. If that is the case, is it possible for you to provide us with the back end and FTP access to your site to check on this issue? You may store your site access at http://stackideas.com/dashboard/site so you don't have to provide these information all the time
