I just upgraded from 2.8.1 to MU 2.8.4a and I am getting an implode error:
<br /> <b>Warning</b>: implode() [<a href='function.implode'>function.implode</a>]: Invalid arguments passed in <b>/path/to/my/mu-directory/wp-admin/wpmu-options.php</b> on line <b>116</b><br />
My MU install is with subfolders and the only plugin I currently have is the multi-site plugin.
I have tried to search the web and forum, but I have nothing on the subject.
Is there anybody experiencing this issue or have a fix for it?
