I have grapgmind installed since a long time and have used it successfully on a Drupal 6 website in english. However, now we're adding a language to our site (dutch & french), we get a network connection error. See images attached: interface ok in english language, network connection error as soon as the language (and thus url, with/nl or/fr) changes, the error appears.
Any quick fix to this, or suggestion?
