Greetings,
I just recently updated to the latest WPMU code on my site, and now I am having some trouble with a custom admin plugin I've written.
I am using the add_/get_options commands, and a form with the wp_nonce_field('update_options') function in it.
This worked just fine before updating, but now I am redirected to wp-admin/options.php after pressing the update button, and I get a question like "Are you sure you wish to do this" (I have norwegian language, so exact english equivalent I am unsure of), and the No / Yes options.
When pressing "Yes", options.php reloads with a message saying "Error! Page for optionsettings was not found" (again roughly translated from norwegian). And the settings are not set.
Any ideas?
