The Redirection plug-in by John Godley has a bug in its current version of 2.1.28.
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permalinks on this site one day and hadn’t noticed that I had already gotten indexed from Google which held allot of outdated links.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.
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.
