In MAMP6, this HTML works as expected:
<img src="images/categories/AG25MM Small.jpg" title="Roto Burs" alt="(image for) Roto Burs" width="600" height="89" loading="lazy">
In MAMP7, it is served with the space changed to a %20, but this gives a 500 error. Even changing the filename in Inspect back to have a space doesn't work.
Somehow Apache is configured to not be able to serve a filename with an embedded space in MAMP7. Any ideas?
