This is the current situation:
If you type in an URL which does not exist in our CMS you will be redirected automatically to a custom 404 error page with a nice layout.
"Outside" the CMS we have a folder which is called /index.php/ . This folder is not affected by automatic redirect. Right now this code of the .htaccess handles all pages under /index.php/ and we get an 404 Not Found page from the server back
RedirectMatch 404 ^/index\.php/.*$
We need to change this in the way that all URLs under /index.php/ including the index of /index.php/ will be redirected to our custom 404 error page (unter /404/404.html).
We can not change the CMS or overwrite the CMS redirection.
I'll send you some example URLs via Private Message if you like.
We can only accept bids by people who can send us an PDF invoice.
