The WordPress Redirection Problem
I changed the permalinks on this site one day and hadn’t noticed that I had already gotten indexed from Google which held allot of outdated links. Well, I found out Google had an issue accessing these pages through the Google Webmaster portal. So from this site I created my redirects and all was great for a week or two.
Overall I like the plug-in and AJAX is always nice for inputting shorts pieces of data. Once I made a change to one of my pages all of a sudden I noticed my front page forwarding to the link I made. I disabled the Redirection plug-in and my problem went away.
The Fix
After looking through the Redirection settings I found setting that was responsible for messing up my front page.
Tools –> Redirection –> Groups –> click edit group to the right of “Modified Post” –> uncheck the Enabled box and save it.
Deep breath after the fix
I’m glad this worked out you just can’t have your front page going to a 404. This has got to be very close to a fatal error in terms of how a visitor will see your sites reliability at that moment. The feature that is faulty in this plug-in is the auto 301 creation process that should take care of forwarding permalinks when you change them in a post or move an article to another section. I thought this was a good feature but the publisher should probably disable it by default if it is not.
Did this fix your problem? Let us know by leaving a comment.
It just keeps us inspired !-)

Thank you sooo much for sharing this fix!
ditto on all issues above and below
YOU So Nailed That!!!
What a blessing – Thanks for the FIX!!!
what was “telling” was even switching themes didn’t make the issue go away – so it was easily isolated as a plug-in conflict – but DARN – that awesome, but wicked group “feature” could be rethunk!
all the best to you and yours on the holiday – YOU certainly made mine!!!
Awesome thanks!!! I’ve been having this problem in many of my sites and you’ve finally provided the solution.
Thanks thanks thanks!

This is a lifesaver. I thought I was going crazy when my blog started this. Thanks for the VERY useful fix.
This problem was killing me. I’m so glad I found your post. I actually have two different groups that the redirection plugin made, and I had to uncheck the box for both the groups: “modified posts” and “redirections”.
Anyways…that is resolved now and my blog is back to normal. Thanks again!
Cheers mate, that was what I’ve been loking for !
Spot on, Thanks!
Thanks you so much, works perfectly! I was like WFT!! Spend hours on the redirection page to check if i did something wrong!
You are a genuis! Much appreciated. I spent many hours trying to figure out why my new page post was coming up when I typed in my blog url! First I deleted the redirection plug in. And then I found your solution and so I reinstalled it and did your steps. Thanks so much, Amy
No problem, I’m glad this fix is still helpful !-)

top notch analysis here, good job man.
also notice for anyone finding this article via google in the future, the redirection plugin is very buggy and takes a while to propigate out, ALSO being logged into the admin panel can sometimes cause problems with cookies and other things, be pantient!
good luck.
Hi,
I’m building a new website, and am having similar homepage problems. The problem is, I can’t seem to make this fix with my limited-access (no upgrade) website. In other words, I can’t get to the groups section in the tools folder.
I was wondering if there was a another plugin that comes second to the Redirection plugin and is less buggy. I would appreciate any insights you might have.
