Yea, my site uses WP Super Cache, and Autoptimize. However, while Autoptimize is an active plugin, is not set to minimize anything right now.
I will not give anyone admin access to the official site, however i have set up a development site which is a direct copy of the official on with its own database. I have already checked, and the same error exists there. Register as a member on it, and i will change the rights to admin. But write down any solution you will find, because when you are done, i will restore the entire site to what it was before you started changing things, and redo the solution myself. This is to ensure that both sites are exact copies of each other.
I have added a admin user for you on this site, you should get the log in information in your email.
Also, i'm currently not using the latest rtMedia version, so you will have to update it when you start your bug checking.
