wrong picture URL when using secured connection (https)

[croulibri]

Hi, I am using piwigo-openstreetmap plugin with Piwigo 2.8.1.

I noticed that the plugin is not working properly when I set $conf['question_mark_in_urls'] = false; in local FileEditor. In that case, the map can't display either the number of pictures (with green/yellow/pink markers) or the thumbnail.

In addition if I am over https (with "Force HTTPS plugin) I still can't see the thumbnail and the link to the picture is not working. Indeed instead of : https://www.XXXXXX.sr/photos/picture.php?/7784/category the plugin send to https://www.XXXXXX.sr:80/photos/picture.php?/7784/category (adding the :80 to the URL)

If I remove $conf['question_mark_in_urls'] = false; in local FileEditor and Force HTTPS plugin, when looking at the map with http only, then everything works fine.

Is it a problem of htaccess ? something else ? My htaccess only include : RewriteEngine on RewriteBase /

Or it is an issue of piwigo-openstreetmap?
