I have a client that needs to be able to edit his pages. His site is going to be multiple languages. I am able to connect and edit pages on my computer. But this is the computer that has the web site files on it. When he tries to use it from either computer (he has 2, desktop and laptop) he clicks edit, then gets an error, something to this nature: 'link contains invalid characters or is too long'. I cannot recreate this error on my computer. Has anyone been had this error and was able to overcome it.

(He is able to edit his other site... so it has worked before)
