Ok, so I’ve had this working on on previous versions of Essential Grid and it works on an old version still: Current SIte where post content inside light box still works
Since updating Essential grid on a development version of the same site, I’m no longer able to get this to work with the error message ‘The requested content cannot be loaded. Please try again later’ being returned.
I understand that all the custom Ajax code that used to be required for this isn’t necessary and was provided with a simple wlakthrough by Themepunch: Video walkthrough
The method described in the vidoe walkthrough now no longer works either. So I’m hoping someone can help because Theempunch don’t even have any documentation on opening post content inside a lightbox (modal window).
I don’t know if the fact that it is a custom post type or that the content is creaued in Cornerstone makes any difference (it never used to and did work at one time as shown in the link above).
