Yesterday we upgraded to Omeka version 2.3, and also upgraded to Simple Pages version 3.0.5. We have a handful of Simple Pages that include PHP, but that code is no longer rendered. Even when creating a new page with a simple "echo" command, the main content of the page is blank, other than the title.
We're doing this using the plain text editor (not the rich text editor). Also, our configuration setting in Simple Pages for "Filter User Input For Page Content?" is unchecked.
If anyone out there has suggestions, I'd love to hear them!
