Thank you for your Replay. Unfortunately, in a clean, latest stable and untouched DW, if I insert the following image:
{{:wiki:dokuwiki-noimage-image.png?200|}}
The result will be a perfectly white page, no error, nothing!
Not nice.
If I don't see the error right away, the image will be never seen again until it will be accidentally discovered and corrected.
How to bring the old behavior where I was able to see a red, yellow, green whatever color or warning telling me there is a broken internal link (or external) ? Thank you.
