We have successfully installed 3 blogs on a server with each blog set to a subdomain. The initial blog was installed flawlessly (with an exception in the htaccess due to the server not being able to rename...however I merely renamed) The second was a bit tricky because while the blog was successfully installed, after hitting the 'take me to the blog' link at the end of an install, we were presented with an empty page. <html><body></body></html> Empty. In Firefox. Safari at least told us that we weren't able to view the site. Interesting. So we enabled errors in the index file and sure enough we could see that many of the config variables weren't available.
Opening database.yaml.php on the blog that was successfully running and comparing it the one that was crapping out showed exactly that... we were missing variables. So to correct the issue we copied over the 'default' values for what was missing and refreshed the page and guess what.
We had a clean install.
So with this knowledge under our belt we moved onto the 3rd and yes, we experienced the same exact issue. database.yaml.stock was successfully renamed and written to up to the admin's email. Nothing else. We opened the file and pasted in the needed variables and yes, once again we had a clean install.
I wanted to post this to see if anyone else out there has had this issue. That is, multiple blogs, subdomains, and install running fine until you view it at which point you are left empty until a bit of debugging shows the database.yaml.php wasn't properly updated.
My intuition points at the fact that we are using subdomains but I'm not a server guru and thus not sure how that is set up. Thanks. Stephen
