6591,infinite redirects with 2.3 and 2.5,danbutcher,anonymous,"I installed both 2.3 and 2.5 in different directories on the same server, and both give me infinite redirects. With default permalink structure set up, I can preview a post or page without problem, but when I publish it and go to view the page/post, I get an endless redirect.

I installed the Disable Canonical URL plugin, and now permalinks work in whatever format I want to make them. 

However, I'm getting error messages in various places:

this one comes up on the write post page: 
Warning: Cannot modify header information - headers already sent by (output started at /home/apache/share/htdocs/english/wp/wp-content/plugins/disableredirect.php:12) in /home/apache/share/htdocs/english/wp/wp-includes/classes.php on line 805

And this one when I publish the post:

I get these when I log out:
