Several Problems with Coursepress Pro

Since updating to Courepress Pro version 1.2.4 I am experiencing the following problems:

1. When I attempt to view previously created course Units I cannot see the content below the "Save" & "Preview" buttons, all that is displayed is "Loading unit elements..." so I cannot see or edit the content, even though it displays on the live site.

2. When I attempt to create Units for New Courses I am unable to enter any content below the "Save" & "Preview" buttons, all that is displayed is "Loading unit elements..."

3. When I select "This is a Paid Course" and click update I get a dialog box that says "There is some information missing or incorrect. Please check your input and try again." but it does not indicate what the problem is. I do have Marketpress v2.9.5.9 installed and Activated.

I am using the Coursepress Theme.

UPDATE: Resolved! I am also using WP Super Cache... just needed to clear Cache.

Thanks for your help!
