For those running ComicPress Manager on their site, there is an update error when installing 2.8. Apparently it is an "undefined function" that exists in the comicpress-manager-library.php file.
That function is: cpm_wpmu_modify_path
Is there any chance someone can find out where the undefined function is and can post a way to manually modify the php file to solve the problem?!
For anyone running ComicPress, you are stuck dead in the water until this update is available. Because the entire manager plugin has to be disabled in order to get site functionality back at all.
