Ok, I logged in, but I got an error message for the JA Slideshow lite
"Response from JoomlArt Updater Service: Sorry, this extension is invalid, unpublished or no longer supported: listlistj16"
Can you also answer me simply with yes/no
a / none of your extensions / templates can be updated via the service joomla?
b / I can manage any backup and restore any extension joomla?
I find your extension interesting except the 2 small problems encountered, I had not found the information clear.
Thank you for the deletion. Can you also remove "JA Builder System Plugin". I don't need it and I couldn't remove it.
Eventually, if you could tell me, how you did it, to avoid soliciting you?
