I suspect I have an issue with the WordPress 'site URL' v the 'WordPress Address' which has been going on some time, but now that I've upgraded to 3.4.1 it's got worse. Depending on which area of the dashboard I wish to work in, WordPress sometimes asks me to reauthenticate. However, when this happens, it seems to go into an authentication loop. I noticed this mainly in the plugin editor, and I let it slide for a bit because I could get around it by editing the files through FTP.
However, now I'm getting the authentication error when I try to use a featured image. I changed .htaccess as I think during the upgrade it rewrote a default, but now instead of getting reauthentications, I get a blank page if I use the browser uploader, and a 'HTTP error' in red if I use the Flash uploader.
As I say, my gut feeling is that it is something to do with my WordPress install being in a different location to the site URL. For example, I've noticed that if I try to get to the 'about' page for the new install at:
it redirects in an endless loop to:
However, when I go to the login page at:
I successfully redirect to:
So the issue seems to be about the redirects, not the featured image problem. I have a hunch that if I fixed the redirect issue, the feature image issue would go away. I have double-checked index.php and .htaccess and I believe they are ok, but is there something I'm missing here?
Also, FYI, my install location is at http://mydomain.com/wordpress but the site address is http://www.mydomain.com . Is the presence of the www affecting things?
