The never ending wordpress login loop
This one was a bit of a bastard to sort out, so I thought I’d pass it on.
How to tell if you’ve got it
1) Load your wordpress site in Firefox, with Firebug installed.
2) Go to the “net” bit which shows you which files are loading.
3) try to go to wp-admin (or any admin page)
The Firebug display will show
login.php
wp-admin
login.php
wp-admin
login.php
wp-admin
Over and over again until it dies
How I fixed it
1) back up the whole site
( faff about for hours, searching for fixed on the internet)
2) delete all plugins using ftp…..
… and it works for the first time in hours
3) copy back akismet with ftp
4) upgrade akismet (there’s an auto upgrade link in the admin bit
5) copy back the other plugins with ftp
So there you go. Hope that helps some other poor soul.
