Ok, on this url : http://rpas-conference.com/documents/
I updated the document which is named “UVS International – Board of Directors in the section “UVS INTERNATIONAL – Reference Information”.
The old version of this document is 170326. When I try to replace it, it doesn t work. Instead of replacing the document of 170326 with the new document of 170421, it creates a new lock of document gallery at the bottom of the page. You can see it at the bottom of the page in the section “Blyenburgh and co – reference information”.
What I expect gallery to do is using the mouse in back office, suppress the old doc and posting a new one when clicking on update. But it doesn t work anymore.
It was working just so fine untill the update of WP 4.7.4
