After performing an upgrade (through softaculous (I am lazy)), I get the 'redirecting loop' error when going to the site.

php info (http://www.voorugezien.nl/info.php)

Update to 1.4.5.5 as just released.

Trying that.

There is no guarantee that softaculous has properly adapted to the current release. Try a manual upgrade.

I did, and it works. Sorry, forgot to post back here.
