Fix “This webpage has a redirect loop” Moodle v2.7 | Lisenet.com :: Linux | Security

Moodle v2.7 installation gives “this webpage has a redirect loop” error.

The Problem

Extracts from Apache access log /var/log/apache2/access.log:

[...] "GET /admin/index.php?sessionstarted=1&lang=en HTTP/1.1" 303 903 
[...] "GET /admin/index.php?cache=1 HTTP/1.1" 303 941 
[...] "GET /admin/index.php?sessionstarted=1&lang=en HTTP/1.1" 303 903 
[...] "GET /admin/index.php?cache=1 HTTP/1.1" 303 941
[...] "GET /admin/index.php?sessionstarted=1&lang=en HTTP/1.1" 303 903
[...] "GET /admin/index.php?cache=1 HTTP/1.1" 303 941

The Fix (Ubuntu 14.04 with Apache2)

Find out the moodle dataroot directory:

# grep ">dataroot.*=" /var/www/html/moodle/config.php
$CFG->dataroot  = '/var/lib/moodle-data';

And remove all content:

# rm /var/lib/moodle-data/* -Rf

Reload a web-browser.

I’m glad it helped :)

Thanks Tomas it worked for me, can you throw some light on why this happened?

I never got to the bottom of this problem, but as dataroot contained “cache”, “localcache”, “session” and “temp” directories, this must have been something related with the server’s cache.

$CFG->dataroot contains both cache and uploaded files. Deleting the whole content of the data directory could be a bit too aggressive.

Thanks. Default Moodle installation has no uploaded files I worry about.

Thank you.
Worked on my moodle, had already tried several things without success, including debug the code, it went into loop and I could not solve. But your solution solved.

Welcome!

Find the moodledata folder. Inside the moodledata there are many folders
1. Delete all from Cache
2. Delete all from Session
Restart your browser.
It worked for me. Hope that works for you.
