Firefox redirect loop

eduguytoo – This is a VERY old post and was about WP 2.8

Did you just upgrade to WP 3.0? If so, can you try deleting the wp-admin and wp-includes folders and reuploading them from a fresh copy of 3.0?

edit, just tried that and still have the same issue, really strange, because yesterday it worked today not,

I’m having the same problem, just started this morning. I contacted my web host and they told me to type in /wp-login.php instead of the usual /wp-admin at the end of my domain that usually gets me into my admin login page. Typing in /wp-login.php worked, I was able to login, but once in my Dashboard I can’t go anywhere. I’m redirected to that Error 404 page again.

Ok, yes, that worked, and yes, it is working now, but I did upload a fresh copy of wp-admin

What is interesting is that once logged in, all is well, very odd, when you get the 404 error, what exactly is the url, or can you see that, copy paste, it you can replace the domain with xxx if you like

This is very curious.

One minor thing, I did add a couple of lines to force wp-config.php to define the site url, if you want to try that I will post it but save a copy of your config file before doing this, just let me know

I ended up logging out then logging back in and I was able to finally get around to do what needed doing this morning.

Very freaky feeling, though, to suddenly be unable to get into my own site!

Just in case this happens again…what lines do you add to the wp-config.php?

…and where would I put them? I’m a complete newbie at all this stuff. Most of what I manage to fix is through stumbling around and getting lucky.

Now before you try this do one of two things, either rename your wp-config.php file to something like wp-config.phpx or save it or both,

toward the bottom of the file you can do this,

under this line should be around line 173

define('ABSPATH', dirname(__FILE__) . '/');

define('WP_HOME','https://www.yourwebsite.com');
define('WP_SITEURL','https://www.yourwebsite.com');

replace your website.com with your real website.com
let me know if that works for you,
