For 3 years Contribute CS3 had worked just fine. The suddenly in Contribute CS3, the EDIT button is grey and the error message just beneath it is "You can't edit this page because it wasn't found on the website or it is in a directory listing". This same message comes up for all the pages on the website. My website designer can access and edit the pages using Dreamweaver. I have contacted our website hosting company, UK2, and they say it is working fine. What can I do to solve this, please, as I need to edit text and photos on the website. Thank you.
