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:
