23418,banned names / illegal_names not being banned,dohman,,"new site registrations are ignoring the banned names i add to the list in network options.

out of the gate the default banned names function works and the system does not let me register any of those default names. the illegal_names value in the wp_sitemeta table is populated with: '''''a:7:{i:0;s:3:""www"";i:1;s:3:""web"";i:2;s:4:""root"";i:3;s:5:""admin"";i:4;s:4:""main"";i:5;s:6:""invite"";i:6;s:13:""administrator"";}'''''

when i add '''''seven eight nine''''' to the banned names field of the network setting page and save the page, the banned names field is populated with '''''www web root admin main invite administrator seven eight nine''''', just how you would expect. but now the illegal_names value in the db is '''''a:1:{i:0;s:61:""www web root admin main invite administrator seven eight nine"";}'''''

notice how the serialized array only has one string now instead of the original multiple strings. once it is saved like this users can register any site name including defaults like admin and root plus the new names i added to the list.

my setup: two fresh multisite 3.5.1 installs. one is on a vps and the other on a local xampp install. no plugins activated nor installed. using twenty twelve theme. these are test installs.",defect (bug),new,normal,3.5.2,Multisite,3.5.1,normal,,has-patch,info@… ipstenu@… mdhansen@…
