I wanted to try this on Bluehost. I DL'd the webinstaller setup-owncloud.php from https://owncloud.org/download/#owncloud-server-web-installer, then UL'd to a freshly created subdomain on my main site (bk.expertek.us) and when I run it, it does nothing except display:
Welcome to the ownCloud Setup Wizard.
This wizard will check the ownCloud dependencies, download the newest version of ownCloud and install it in a few simple steps.
ownCloud – web services under your control
I check the folder - no new error.log check console in FFox, nothing. no new files.
Next, I DL'd the original install file. owncloud-latest.zip and place it in the domain folder. re load the webinstaller.
still not working. try in IE. nope. same thing.
tried renaming the webinstaller to oc.zip - NOGO.
finally, extracted teh installer, and loaded index.php - seems to start ok, asking for my database stuff.
Just not sure why the installer didn't work...
