I have an issue with a fresh install of WordPress into an addon domain. After the installation, accessing the login and admin pages using the addon domain URL, I get a blank white page.
I have a working install of WordPress 3.4.2 for development in a subdomain of my host site:
This has been working fine. The following all work fine
The directory structure is as follows:
I have installed WordPress again, to become the live site in an addon domain, using a separate MySQL database
The add on domain is http://www.addon.de. It is registered with a different host (as it's a .de and can't be transferred to a UK host) and the domain servers are set to point to those of the hosting provider of http://www.mainsite.me.uk
I installed WordPress file manually using FTP into the following directory
(mcedward being the user id for the mainsite.me.uk hosting plan).
The install ran using http://www.addon.de/wp-install.php and was allegedly successful and it prompted me to login. The login link URL is:
Mmmm... why not http://www.addon.de/login.php?
When I use the following URLs it doesn't work, just displaying a blank web page (white screen of death?!) with no message. (using Firefox or Chrome)
(Strangely I got the log on screen once! It seemed to redirect to http://www.mainsite.me.uk/addon.de/wp-login.php and showed all this in the URL - which I don't want shown)
The current live site is in the /home/mcedward/public_html/addon.de directory (plain html). If I rename it's index.html then the following displays the default WordPress page as expected for a new install
If I use the following it works
Note: it's the same using Firefox or Chrome. Slightly different in IE. With http://www.addon.de/wp-admin/ I get the following message
"This content cannot be displayed in a frame" with the option to "open content in a new window". When I take this option it works.
I have tried one forum post suggestion which was to change the site URLs in WordPress Settings-> General from http://www.mainsite.me.uk/addon.de to http://www.addon.de. This left the site inaccessible.
I set WP_DEBUG to true in the config file but the white screen of death appears without messages and there is no debug log file created in wp-content (as I was led to believe would be the case by another forum post).
There are indications in other 'white screen of death' related postings that .htaccess files might have a role. So, for information:
There is one in /home/mcedward/public_html (empty)
There are a couple associated with the development site are a couple of .htaccess files, one in each of
/home/mcedward/public_html/dev-subdomain/wordpress (presumably setup by WordPress)
/home/mcedward/public_html/dev-subdomain (set up to password protect the directory using cPanel).
I renamed these to remove any influence it may have had but the behaviours remained the same.
I'm stumped as to how to get the most basic WordPress admin page accessible through the addon domain directly. I haven't yet tested whether it works properly when accessed via the main site domain or the subdomain that is created when the addon domain is created but I'm fearful that the install will be unstable. I've been advised by the hosting company not to use the subdomain, which is fine as I don't want to, but I cannot figure out how to make it work just using the addon domain URL, which is surely the point of addon domains.
