Thanks for your reply, Trent.
Yeah I did clear the cache and switched browsers.
One of two things always happens. Either the browser uploader is shown and insert into post doesnt work as described before OR the add media window that pops up...just shows a login box. And when you do login again, it takes you to dashboard. If you login at both the mapped domain and the blog subdomain, it still shows the login box when accessing the uploader.
With IE7 I get some nasty permission denied debug errors when type a post title and then click the Post Content box or (if I get far enough) when I access the browser uploader. I think it maybe related since this doesn't happen on blogs that have domain mapping disabled. Here's two of them.
First. This one occurs just after trying the browser uploader. (this is just the highlighted problem area)
.password);else c.open(type,s.url,s.async);try{if(s.
Second. This occurs sometimes by just accessing the Write>Post page.
(function(){document.open();document.domain="cariblogger.com";var ed = window.parent.tinyMCE.get("content");document.write(ed.iframeHTML);document.close();ed.setupIframe();})()
All the mapped blogs have this issue and they don't have any plugins activated on them. You can browse the mu-plugins folder on my site, but I don't think any of those could be the cause of this.
I'm running 2.6.2 ..what versions were you testing against?
