Whenever we try to use something that has TinyMCE open up in a frame (such as trying to add a hyperlink), we get the following message:
Unsafe JavaScript attempt to access frame with URL http://sub.domain.com/forums/?new=topic from frame with URL http://sub.domain.com/wp-content/sp-resources/forum-plugins/tinymce-richtext/tinymce/themes/advanced/link.htm?mce_rdomain=domain.com. Domains, protocols and ports must match.
My guess is this is caused because the mce_rdomain is just “domain.com” instead of “sub.domain.com”, but there seems to be no way to fix this.
Any ideas? This is a pretty major issue.
