I have some blogs that constantly end up in "too many redirects" warnings and similar error messages. What fixes this problem? Going to permalinks and selecting custom, putting in the post name, clicking submit and we're in business again and no redirects. It shows in WP the post name afterwards and it's fine. Then for an unknown reason I get this happening again out of the blue. Same remedy and it works again for an undefined period of time until it happens again.
I've seen it happen to others here and I'm wondering if others have discovered a cause for this.
Of note - I just found this concerning the Yoast WordPress SEO plugin. For some reason it is a problem on some blogs but not others. I will try to turn off the category fix. http://wordpress.org/support/topic/too-many-redirects-error-and-permalinks?replies=25
