Hello, I have the same problem too but it depends on the plugin. When I change set up of some, I get a 404 page. With other plugins, I’m redirected to the dashboard of the site with this url “…/network-blog-name/wp-admin/?c=1″.
I tried to modify the admin page of BP-share-it plugin where I changed action=”options.php” to action=”../options.php”. It worked but not for other plugins…
Hello, I have the same problem : I installed WP 3.1 then BP 1.2.8 and the plugin BP Links 0.5. Everything worked fine till I enabled WP multisite… Since then, the plugin seems to work well but the plugin control does not show anymore neither in the network admin dashboard nor in the blog admin dashboard.
How can I fix this, please ?
