texte = Hi Tom, Thanks for the reply. I actually solved this problem a long time ago, but it's been so long that I forgot how I did it until last night ... The solution is simple. Just replace the value in the Message field of the TemplateNotFound record in the ErrorMessages.db with this [include /error.tpl] tag. Then put this line into the .htaccess file that resides in the website's document root folder: ErrorDocument 404 /error.html Apparently that's all it takes on WebDNA 6.x and Apache to insure that all 404 errors on the entire website are handled by the /error.tpl file. What's nice about this is that a [thisurl] tag inside the /errors.tpl file returns the original request URL, not the URL of the error page ... so we know which page each visitor was trying to retrieve. This means we can silently redirect him to the new destinations of a recently moved page -- or post our own custom error message when the page truly does not exist. Ony one problem with this method, it won't work if your host has you on a shared webdna server (without your own sandbox) and will not give you access to the ErrorMessages.db. So it is much better to have your own sandbox where you can edit your own ErrorMessages.db and not affect anyone else's webdna sites on the same server. :) This solution works fine for non-existing pages with webdna suffixes. But when a non-existing file with a NON-webdna suffix is requested, the following webdna error is appended to the bottom of the /error.tpl page: Error: template security preferences do not allow remote access to files with that extension This error should be easy to eliminate by getting rid of the value in the Message field of the TemplateSecurity record in the ErrorMessages.db. Just make this field blank/empty to suppress it. Or if you prefer to hide this error only on the /error.tpl page you can try putting a beginning HTML comment tag immediately after the include tag in the ErrorMessages.db like this: [include /error.tpl]
