Summary: the images are not showing up.
Problem: fetch.php seems not to get the correct namespace for the image and if the "start" namespace is denied by default the image is not shown.
i.e: @conf/acl.auth.php
* @ALL 0
i.e
https://example.com/lib/exe/fetch.php?cache=&media=namespace:figure.jpg
shows up "Unauthorized"
by adding "id=namespace:figure.jpg" argument it gets the namespace correctly:
i.e:
https://example.com/lib/exe/fetch.php?cache=&media=namespace:figure.jpg&id=media=namespace:figure.jpg
the image is shown
Temporary solution: a "workaround" I did was
@common.php line 496 (in the end of function ml)
just before the line:
return $xlink;
add:
$xlink .= $sep.'id='.$id;
ps: problem doesn't occur with administrator users(who can access anything)
i.e: @conf/acl.auth.php
* @ADMINISTRATOR 8
