Continuous login loop to wp-login.php

@matthew, first let me explain why I wanted no random suggestions – once a post in this Forums gets a reply, even if it’s nothing more than a question for the OP, it then drops off of the list of posts without replies……that list (posts with no replies) is where many moderators and very experienced WP users go first to help those folks that no one else is helping……if my Post isn’t there, which now it won’t be, it’s less likely to get attention from someone who is more likely to be able to help.

To answer your questions, this has nothing at all to do with the version of WP, because it has been going on for more than 5 years. Folks have had this problem with every version, including 4.2.4.

I do NO automatic updates, period. That is dangerous, so I have automatic updates turned off. I do them manually when the time is right and I’ve taken every precaution.

It is not a hosting company problem. I have hundreds of websites on the same hosting package – all run fairly current versions of WP – and only ONE website has this login loop problem.

And yes I did restore from a recent backup without success.

@ayosten – I’m truly sorry you’re having this problem also, and I appreciate that you’d also like to find a solution. However, please don’t take this the wrong way, I mean this as constructively as possible, but please don’t hijack someone else’s thread to add your own “me too” UNLESS you have some solution to offer or a VITAL clue. Otherwise, your “me too” just causes a post to drop out of the “no replies” list, which as stated above means fewer moderators or experienced WP users will look at it. Your best course of action is to *watch* the thread to see if a solution is offered, AND/or start your own thread. Often the Moderators may combine threads at THEIR discretion, if it’s an identical problem with an identical cause.

ALSO, it does not having anything to do with your upgrade. This has been going on since version 3, maybe longer.

@jan, great thought, but I’m on a shared-hosting package with 1&1, and the htttpd.conf file is a singular one for all sites in my package. It isn’t modifiable, customers can use .htaccess to make certain changes, so I compared the .htaccess file between several working sites and the one that isn’t, and they are identical.

@otto, also a great question, but I did check those options in the wp_options table and they are set correctly and do match the URL string in the browser. And no whole-site caching, I don’t use any caching plugins or CDNs at all, it’s a fairly small site, just a few pages, not particularly image or media-heavy so really no need for caching.

UPDATE: I went to bed last night with this still looping back to the login page, got up this morning and answered Jan’s and Otto’s questions, then went and tried to login again on a lark. WITH NOTHING CHANGED by me overnight, it now lets me login.

I HAVE absolutely NO idea why it’s now working so sadly I cannot post any solutions……I’ve just checked WP and all plugins, and there have been no auto-updates to anything (I have that turned off), so I’m equally as stumped as to why this has suddenly resolved itself as I was about how/why it occurred. It’s a 24-hour mystery.

@jan – Thanks! I do make regular backups, I use the wp-dbmanager plugin to automate it, works very well. 🙂
