Hi!
I've been working over a number of sites into processwire, but I have come across a strange bug I cannot wrap my head around.
I'm using method #1. Single wire directory, multiple site- directories with index.config.php and config.php set up properly.
I've had no problem setting domains in the configs up until this point. www and root domains are loading perfectly. However I tried to add a subdomain value 'new.domain.com' and I have put the bits in all the right spots. I get a 500 Internal Server Error.
If I change the subdomain to something else, same deal. Only domain.tdl and www.domain.tdl entries are working.
Any thoughts? I'm using the latest stable 3.X branch.
