TOPIC: issue: thumbnail remain in Loading

using joomla 4.3.0-rc2 and Highslide effect, when I click on the thumb remain in Loading, without open any popup

I have the same problem, but I found out that I got a 404 in the logs:
GET /plugins/content/smartresizer/smartresizer/js/highslide/graphics/outlines/rounded-white.png HTTP/1.1" 404

The problem is that this Joomla installation is not in the document root but in /mizapf. So the proper path for GET would have been /mizapf/plugins/content/smartresizer/smartresizer/js/highslide/graphics/outlines/rounded-white.png

I guess there is a path issue with this plugin option.
