(for info, i exported my database, put the WP files on the new FTP, replaced the wp-content folder with the old one (including theme, plugins, and medias), installed WP, activated my theme and plugins, then imported the file generated at the export (with the attachments).
The site transfered well, I changed the intern permalinks using velvet blue update url.
Now my site is 90% the same as before the transfert, but the slideshows are ampty. They are all present in the slideshow tab on the dashboard, all posts deploy a slideshow...but empty (no image, no text, no link).
Thank you in advance.
