Need A Joomla Expert

On one of my Joomla sites, I am unable to edit individual pages when logging in through the front end. I can log in, but the pages that load are static. For example, I'd like to edit the "Editors Review" on the following page: [login to view URL] However, when I hit edit, the page that comes up is corrupted. If I open it in a new tab, everything displays correctly, but the "Submit" button does not work - it stays static. I hired another Joomla expert to fix this, but they were unable to solve the problem. If you have seen this issue before, please bid on this project, but payment will only be made of this problem is resolved. I look very forward to working with you!
