Not sure why this thread got overlooked.

As far as I know the choice of subdirectory or subdomain as an mu blog option on install doesn’t matter. I have seen complications where people install mu in a subdirectory under the document root and then have chosen the subdirectory blog option.

I haven’t been able to pin it down but some weirdness crops up in that case. In both cases it’s been difficult to determine exactly what the problem was. They had difficulties getting their shared hosting provider to cooperate. It’s kinda tough to pin things down when getting access to error logs is like trying to get an audience with the pope.

There are no ‘subdomain’ only specific requirements.
