Redmine

Hello,

I use plugin tab iframe (A Redmine plugin which adds new Redmine tabs to embed content from an iframe on a per-project and system-wide base) : http://www.redmine.org/projects/redmine/wiki/PluginTab

The plugin have no problem but when i add my iframe-link (Webmail Roundcube) there is no display. However it works with other links.

Can anybody help me out to resolve this problem?
