Hi again -
Ok, a similar problem has cropped up again today, for a different networked blog I'm importing into my mu installation. Safe mode is still off.
Today I'm getting an "unable to create directory" error message. Yesterday I had this same problem initially and called my host to have them set ownership of /2/ to match the ownership of my other directories in the main domain. That fixed it. So I called them to do the same for the new blogs' directories (e.g., /blogs.dir/4/) but the ownership was already correct.
There's also another variation from yesterday. Whereas yesterday the directory in which wpmu wanted to put the import blog was .../wp-content/blogs.dir/2/files, today for the new blog it wants to put it in .../wp-content/blogs.dir/4/files/2010/06. I know the 4 is correct, but can't figure out why it wants to put it in a year/month subdirectory. Permalinks are set to %postname% only. I assume I don't really want the entire blog imported into a year/month subdirectory, right?
Can anyone help me? I'm stumped again! Thanks!
