I installed wordpress 3.0 beta 2 on a new site and tried the multi site feature. I've set it all up with domain mapping so I got two domains now controlled with one installation.
I did a network activation for the nextgen gallery on the main site without any problems.
at the SUPER ADMIN nextgen gallery options page I entered the %blogid%/ thing.
everything is working normal with the plugin.
on the second site it asks me to upgrade nextgen because it is out of date.
continue... >> leads me to the same page before. (upgrade because out of date) At the moment I can only upgrade and continue, upgrade and continue and so on.
on the main site all is running fine.
latest versions of WP and nextgen gallery are installed.
Does anybody came across this problem already?
