I come back after the reply of my web host . They recommend me to uninstall my JAlbum and re install the program . What do you think about this solution ? I understand from this reply that the problem in not from my web host but from JAlbum . In any case if you are able to help me it will be very useful for me . Thanking you beforehand for your help
Seems like a reply from an inexperienced support person. Uninstalling+reinstalling jAlbum doesn't solve this problem. It is an error message that's delivered from the server, but you can try lowering the number of simultaneous transfers/connections under Preferences->Publishing. Set it to 1 and try again. (It will lower the publishing speed but might help)
