2.7 upgrade – Redirect Loop error

OK, The reason my main page wasn’t pulling in posts and a sidebar was that I had some other plugins disabled. Not sure how that happened.

What I did was:
1) Reverted fully back to previous version. Made sure this worked fine.
2) Deleted all files, except for config file and wp-content.
3) Reinstalled 2.7. Made sure all previous plug-ins were active, except for the “disable canonical redirection” one, which I had ftp’d out there earlier.
4) Main page still went into redirect. Admin prompted for database upgrade. When I approved the upgrade, I saw it update the .htaccess file. I deleted this and put back the old version of it. Main page still looping on redirect.
5) Activated that “disable canonical redirection” plug-in. Main page (and, of course, other pages) pulls up fine.

Thanks!

I can’t get into wp-admin to activate the plugin. Anybody know how to get around that?

Just had the same issue for me on https://ambermariebently.com, I had the following 3 plugins:
1) Filosofo’s remove dashboard
https://www.ilfilosofo.com/blog/2006/05/24/plugin-remove-the-wordpress-dashboard/
2) Role Manager (not updated still):
https://sourceforge.net/projects/role-manager
3) Filosofo’s database backup:
https://www.ads-software.com/extend/plugins/wp-db-backup/

Might have been remove dashboard for me – regardless, I dumped that and role manager, and I could log in again. I have a feeling remove dashboard was trying to redirect to a sub page, and then that trying to send back.

Regardless, I recommend when you have these problems do two things:
1) Make sure the folder for Admin and it’s contents are set to 755, or rwxr-xr-x (everyone can read and execute, but only user can write)
2) copy your plugins locally, then delete them from the server

The disable redirection is a bit of a funky hack, you could be covering a larger issue, like I had above.

Thanks everyone, I hope this helps you a bit!

If you have redirections in your site document root directory
the problem could be mishandled links in PHP code for some plugins.

I had a redirection problem with wp-reCAPTCHA. The options form pointed to $_SERVER['PHP_SELF'], who fetches the raw address of the script file and thus gets scrambled by actual site redirection, since form actions are delivered via http server (apache 2.0) and not directly by the OS. The actual page would never be reached and WP got lost in endless login forms.

So I hacked the plugin code (version 2.9.2, wp-recaptcha.php, line 696), pointed the options form action to $_SERVER['REDIRECT_SCRIPT_URI'] and it worked like a charm.

If you can – and that is the case – try hacking the source code of the broken page, point out the missing link, grep its surrounding code into the plugin directory and var_dump the variables used in forms and link options. Quite messy, I know, but that may help here and there.

Before you try anything, try removing the object-cache in your wp-content folder if it exists.

Hope this helps

With WP 2.81, disable canonical URL redirect plugin worked for me, whereas disabling all plugins did nothing.

However, why can’t I use canonical URL redirects!!? They’re there for a reason.

So annoying. And only at https://christophdollis.com/

My other sites work just fine.

Incidentally, it was my posts page getting the redirect loop error, not my homepage. WordPress is installed in its own directory not the root, if that matters.

Just upgraded to 2.8.6 and had this redirect error, even with all plugins disabled. The “Disable Canonical Redirection” plugin worked for me, thank god! I appreciate the advice!
