Here's what I did:
1. Installed & everything looked good w/default Blackcandy theme
2. Uploaded new theme (iorange2b) to my themes folder .
3. edited mysite/_config.php to reflect the new theme.
4. Reloaded my site (used ?flush=1) aaaaaaand... blank homepage.
Any ideas? I know the procedure is simple, but it's actin' all fonky. grrr.
Thanks for that. Provided I'm looking at the correct error log, the thing I see that appears the most is a missing robots.txt file. Would that have any bearing? I just viewed another page on the site and the updated theme is showing up, not just a blank page (see http://www.djmedi4.com/about as opposed to http://www.djmedi4.com)
