Hello,

I need some help please. I have an "null" album that I can't manage. It will not allow me to edit the name, the edit album icon takes me to the Piwigo Administration page and Add pictures returns:

Piwigo encountered an irrecoverable error
[Hacking attempt] the input parameter "album" is not valid

#1    check_input_parameter /var/www/pm01ex.com/gallery/admin/include/photos_add_direct_prepare.inc.php(92)
#2    include_once /var/www/gallery/admin/photos_add_direct.php(140)
#3    include /var/www/gallery/admin/photos_add.php(73)
#4    include /var/www/gallery/admin.php(406)

Looking at the album properties page, there is an album with name "/jc" which was added by mistake, a typo. My best guess is that the "/" is causing havoc and this is the so called "null" album.

I am the system administrator so have access to the server and phpmyadmin. I don't want to touch anything until I have some feedback from you guys.

Many thanks in advance for your help.
