Sure thing. This is the URL Below.
http://sitalcollege.com/edu/index.php/programmes/certificatesIf you navigate to the, Corporate Training, Diplomas, and AIB pages within the menu, you can see that it exists in all of these and gives the same issue.
Now i did observe something. If I displayed the page titled "portfolio" under the menu "Pages" , the exact same way that it was displayed in the DEMO, it works. If any of these were to be placed in the heading "pages" ( as in the DEMO ), they work magically. I tried to use these pages, ( certificates ect) under the heading pages, but once i changed the menu name from "pages" to whichever menu name i chose. The portfolio code would seem not to work.
